- Hello fiends,
In today's video, we are going to learn to make a tesla coil for wireless transfer of electricity. A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. Tesla coils can be used for wireless transfer of electricity. It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. A fluorescent lamp lights up when brought near the tesla coil. This is due toe the flow of electrons in the lamp which is caused by the high voltage generated by the tesla coil.
Parts needed for making tesla coil
1. 2N2222 NPN transistor
2. Enameled copper wire , 20-28SWG, 10 metres length.
3. 2.2 kilo ohm resistor
4. 9V battery
You can watch this video and learn step by step, how to make a tesla coil.

After long and hard journey, I finally got my working slayer exciter thank u brother It worked after 34th try it was actually the coil winding problem but I didn't know it and kept changing the resistor and transistor but it worth it
Ooh..that is nice friend. 34 attempts to make it right!!!. I am so glad that it got right finally!!. Can you tell friend what was the coil winding problem, so that other viewers will benefit from your experience.
Sir Can we use tungsten bulb ?
Hi instead of ball what we can use??
Can you please tell me which one is the primary and secondary coil here?
Sir can I use an old not working CFL bulb
It will work or not
Yes friend. Old CFL bulb will also work. Because the bulb lights up by the flow of electrons in the flourescent coating. So old CFL bulbs which are not working will also light up when brought near the tesla coil.
@@Science_4U_ Thankyou sir for your rapid reply🙏
Sir I pray for you to reach 1m subs soon 😊
@@MrCreatorSounds Thank you so much dear friend..🥰❤️🙂
Sir I don't have 2N2222A NPN transistor can I be able to replace it with any other transistor
Its not working
27 gauge insulated copper wire
10 inch pvc pipe
20 k ohm resistor
Transistor 2n2222(substitute) or similar
But my transistor heating too much and the led inbuilt in circuit is also not glowing .Is the transistor faulty? Help me please.
Hi friend. The transitor will heat up so much because it handles a large amount of current through it and hence this is normal. Make sure the connections are correct. Also, the battery gets discharged very fast in this circuit. So ensure that you are using well charged batteries. Also the bulb has to be brough near the coil in different ways and at one orientation, it will glow up..
9 v battery k place me 3.7 v lithium ion battery kr sakte h ?.
Is project mein jyada voltage acha hai. Toh 9V aur 12V, 3.7V se bhi acha hotah hai. Jyadha input voltage is circuit mein deta hai toh jyadah output voltage bhi mil jayega aur bulb jaldi se jal jayega.
should I buy 28 awg copper wire for this?
Hi friend, You can buy any wire size from 20 awg to 28 awg.
For lower than 20 awg, wire diameter will be more. So making around 300 turns will take lot of space..
If you buy wire higher than 28 awg, the wire diameter will be too thin. So winding will be very difficult..
So awg 20 to awg 28 will be ideal for this project. Somewhere in middle like 24 or 25 awg will be best with a wire diameter of around 0.5mm
You have to buy insulated copper wire..
Sir aapne PVC pipe me 1 feet length likha hai to vo kitna centre meter hoga...?

@@bhavyathacker6097 woh insulated copper wire hai na? Insulated copper wire nahi toh woh kaam nahi karega..
@@Science_4U_ sir mene jo copper wire use kiya hai wo insulated hai ke nahi vo kishe pata karu?
Sir i made Tesla coil by following your instructions but it's not working but the transistor becomes very hot
Hmm..yes friend. Since a large current is flowing through the transistor, it becomes hot very fast..Which bulb have you used to check the tesla coil?. Only bulbs with flourescent coatings will work. CFL bulbs are the best..
Dia of pipe matters??
@@arshina6891 No friend. It doesnt really matter. The most important thing is to have atleast 250-300 turns of copper wire on the pipe..
Bro can we use 2n2222h. Transistor
Yes..sure friend. You can use that..🙂
Super👌👌
Thank you..🙂
would it burn If i power it with 12v 16A led powersupply.
No friend. No problem at all. Higher current capacity power supply does'nt matter at all. The circuit will consume only the current that is required.So there will not be any issue..
canyou tell me the no. of winds in secondary coil and can any wire can be used

Hello. I built the circuit and the transistor is heating up. I don't have a CFL bulb as of right now (LED bulb won't light up). Is mine faulty or okay?
You need a CFL bulb to light up friend..
@@Science_4U_cfl not lighting up
@@Science_4U_does it need to switch on for a long time
@@Science_4U_How long does it need to be switched on? I am worried the transistor will blow
@@Science_4U_ pls answer CFL not lighting up
Can i use small diameter pvc 25 gauge copper wire
Yes friend. You can use. Just make sure you make atleast 250-300 turns of coil on the PVC pipe..
@@Science_4U_
What use diameter of pipe
@@Science_4U_
Thr rotating of copper wire on pvc clockwise or anticlockwise
Hi friend..I used 1 inch diameter PVC pipe..
@jalandhra001 you can wind the coil in clockwise or anticlockwise direction..Both will work.
2.2k or 22k resistor ? Another site said 22k. Would that make a difference?
Hi friend. I have also seen videos with both values of resistance 2.2K and 22K. I think both should work. I have used 2.2k only and it worked.
Thanks. I have both. For some reason I cannot get this to work
@AngelaYer okay friend. It is a bit tricky to make it work. Please check the following.
Have you made atleast 250-300 turns of coil?
Is the resistor heating up?. If it heats up, it is drawing lot of current and it shows it is working properly
Use a high capacity fresh battery. This circuit drains battery very fast.
Use a new CFL bulb
Yes, I did all of these. I took it apart about 8 times, using new resistors and transistors. I’m happy to say that after trying again and again, it finally worked! 👏🏻 Thanks for your replies!
@@AngelaYer ooh..great!!!!.So glad that it finally worked.🙂❤️. For me also it took a lot of attempts to make it work. I would bring the CFL bulb close to the coil in different orientations many times. Sometimes bulb will not light up. But at a particular attempt in a particular orientation, it just lights up. This was my experience.
Sir PVC pipe se hi hoga aur koi pipe se nahi hoga ?
PVC pipe best hai..Metal pipe nahi kam karega..metal pipe charge leakage ho jayega..
One day you are gonna 10 million mark and you will remember my name that I was one of your early subscribers
Thank you so much dear friend..🥰🙂🤝👍
Words like these are the inspiration for making more such videos. Thank you so much. Please share the channel with your friends whom you think may like it..Thank you..
Bro the ball should be inside of Aluminium foil or out side
Hi friend. The Ball should be in inside the aluminium foil. The aluminium foil should cover the ball.
Hi instead of ball what we can use??
Bro we need to use only CFL bulbs
Hi friend..The tesla coil works by generating very high voltage. A CFL bulb has a phosphor coating which when brought near the tesla coil generates electrons due to the high voltage by tesla coil. This flow of electrons causes a glow of light. LED bulbs may glow due to the high voltage, but since there is no phoospor coating, the glow will be very weak..CFL bulbs are the best choice for using with tesla coil..🙂
Ok 🫡
sir why is my tesla coil not working?
Hi friend, the tesla coil that you had made should have definitely worked, if you followed the same instructions as shown in the video. But from my experience also, it is not very easy to work. You will have to try with several CFL bulbs, move CFL bulb near and far away from the tesla coil. At some point bulb will glow. Also please note that battery gets drained very fast. So you can try with a higher capacity battery which is fully charged. Also please check if transistor is in good condition and working. Try with another transistor and see if it works.
To not enough voltage
Hmm...yes..if the battery voltage drops, then the tesla cpil stops working. You have to provide a high capacity battery with sufficient voltage, then it will surely work...
@@Science_4U_my Tesla coil is not working but transistor is heat I use 9v battery
@@artbytanmay353 Okay friend. Transistor heating means circuit is working. Try with different bulb in different orientations. At some instant, the bulb will glow..
Sir neon bulb jlega kya
Haan..jalega..
Btw, why this tesla coil doesn't need capacitor?
Yes. There are tesla coil circuits with capacitors. But in this circuit, capacitor is not required..
Sir my swg is 21 which diameter i take
For 21 SWG also, you can use PVC pipe with 1 inch diameter..
Sir copper wire ke 250 se 300 Tak kitne bhi round lga skte h 275 bhi 😩 kyuki Mera work nhi kar rha h Syd yhi problem h
Resistor me prob hoga tumhare 1k, 1k ka 2 series me istemaal kro
Super
Thank you dear friend..🙂❤️
can you provide the circuit diagram for this
Brother one doubt what is the length of pipe
Length of the pipe should be sufficient to hold all the 250-300 turns of copper wire. I used 1 feet length of PVC pipe, wound all the turns and then cut off the remaining length..The total length required was around 150 cm..
Sir i have little gap in my tesla coil while winding did it work
@@mr.a.akshay2499 No problem friend. It is better to wind tightly so that you get more flux density. But with small gap also, it should work👍
@@mr.a.akshay2499did it work
Sir can i use 16 swg
You can use 16swg. But it will be very thick at 1.626mm. So it will occupy a large space for getting large number of turns. Make sure you are making atleast 250-300 turns..
Sir I am doing my school project by making a Tesla coil and sir can I use HLC bulb and tell me what work we should do for making this succesfull and how many chances are there that it will we successfull
@jokhosa332 Hi friend. Tesla coil is definitely a woking project. But some people don't get it working in the first attempt. This is due to following factors.
1. The winding of the coil should be very good with atleast 250-300 turns.
The battery drains very fast. So we have to use a high capacity battery.
This tesla coil works by generating high voltage spikes, which causes electrons to flow in phosphor coatings in bulbs. So in my understanding, it is better to use CFL bulbs which have this phosphor coating. It may not glow at first, because the tesla coil that we make are not very powerful. But you can bring the CFL bulb near the tesla coil, rotate in several direction and at one instant, the bulb will glow..
Sir can I use any type of transistor
No friend. The transistor should have very high current rating. 2N2222 is the best one. BC 547 will also work, but the connection will change.
Kam karega pakka sir ,,,
Ek problem h utna voltage to nhi banega ki cFL glow kare ,,,,I think
It will definitelywork..if it is not working, you have ro increase the number of turns in the coil..
Also, the battey will get drained very fast..So after sometime the circuit will not work because the battery has drained. Make sure you connect a battery with large capacity..
.
2.2 kilo ohm or 22 kilo ohm??
Both should work friend. I used 2.2 kilo ohm and worked for me. I have seen several videos where people used 22 kilo ohm also. So I think both resistors should work..👍
hi i use 24 guage 300turn
16guage 3turn
20k metal film resistor
2n2222a transistor
9v battery
but why is not working sir can u explain me about it please reply me please
Hi friend. You have used the correct components only. Can you check whether the transistor is heating up?. If the circuit is working correctly, transistor will get heated up because a large current is flowing throug it. Also use a new battery as it gets discharged very fast. Are you using CFL bulb only?. Only CFL bulb will work. Also from my experience, the bulb will not light up at first. We have to bring bulb near the coil in different orientations. In a particular orientation, it will light up.
@@Science_4U_ although the transistor was heated up, rotating the CFL 10w light bulb around it, the bulb didn't light up, I thought it was because of the guage of coil. Is it really relevant with the gauge? 24awg for secondary, 16awg for primary and wind those in 1inch PVC but no aluminum foil on top
@triple4179 gauge doesn't really matter..Have you used a new battery?. Try to use a battery with atleast 9V.
@@Science_4U_ is it ok to use the 12v 100ah car battery from my garage?
It is technicalpy possible, but Better dont use that. Because if something wrong like short circuiting the coil, a large current flows overheating the coil and it will cause serious injuries.
What would happen if I used a cord for a wall outlet for this instead of a battery
It will work friend. The chord output should be around 9-12 volts DC...
@@Science_4U_would it work with a 20v power supply?
@@teunlll yes..it should work!!! The maximum.voltage for the 2N2222 transistor is 30 volts..so 20V power supply should definitely work..
Hi sir im going to make this for my project can you answer my question if it dont work
@@danceislife979 ya u can do it in your school project, ofcourse it is a working project
I did and it's not working
@@danceislife979 It's working my friend just check your transistor is heating or not
If it is heating then your project is alright if it is not heating then the transistor has been gone also check how many times did u winded the wire
Note:This project will only work on CFL bulbs and not on LED bulbs
What is the diameter of this 20 -28 swg wire
20 swg = 0.914 mm diameter
28 swg= 0.3759mm diameter..
Though I have mentioned 20 to 28 swg wire,
24 to 26 swg will be best suitable for this project. 24swg is 0.559mm diameter and 26swg is 0.4572mm diameter...
@@Science_4U_ thank you so much sir..
@@bhavyathacker6097 okay friend..👍
Depends on EMI
Ya..sahi hai..
EMI badne keliye coil number of turns bahut jyada hona padega..👍
Mine is transistor smoking and it is not working pls help me
Hi friend. In this circuit, the transistor gets really hot because it handles all the current that goes through the tesla coil. So we should not keep it switched on for long. Also check the resistance value and the connections. Also which bulb are you using?. A CFL bulb or any fllourescent bulb only will work for this project.
Kitna watt ka resistor chahiye
1/2 watt or 1 watt or 2 watt resistor acha hoga..👍
@@Science_4U_ thanku
Bhai ye project sach me kaam krega na ??.
Hi dosth. Yeh project bilkul kaam karega. Lekin kaam karne keliye bahut aasan nahi hai. Thoda mushkil hai. Woh coil winding ache se karna padega. Aur is circuit mein battery jaldi se discharge ho jayega. Isliye ek naya fully charged battery bhi use karna hai..
@@Science_4U_ thik hai dost
Kal bnake btata hu kaisa hai
@the_royalgamer484 dik hai bhaiya..try many times bringing the CFL bulb near the coil in different directions. After several attempts, one time bulb will light up..
@@Science_4U_ ok dost
What is the maximum voltage i should use in this circuit?
Hi friend. You can use upto 12V batteries without any issues..

Sir my tesla coil is not working
And sir inside foil it is nessaray to keep that ball
Sir my wound of copper is 150 to 200 turn will it work
Sir CFL of 5 vot will work plzzzz tell
Hi friend..it will work. You have to make around 250-300 turns for it to work properly. Also, the CFL bulb has to be brought near it in different orientations..in one particular orientation, it will light up. Also please check the transistor if it is heating up. If it is heating up, then it is working. Also use new battery. It will get discharged very fast.
Thanks sir
Does not work. does not turn on
Hmm..okay friend. This is actually a working circuit only. But it is a bit difficult to make it work. Have you used CFL bulb only?. You will have to bring the bulb near the tesla coil multiple times in different orientations and in one particular orientation, the bulb will glow up.
Is your transistor heating up?. If not, then it is faulty.
Also, check battery. The battery should be fullly charged to get good voltage output from the tesla coil.
@@Science_4U_ the resistor is not getting any hot and the 2n2222 doesnt get hot too
@Lacx_gt Hmm.. okay friend. The 2N2222 transistor is supposed to get very hot since it is handling large current in the circuit. Either the connection is wrong or the transistor is faulty. If you are sure that the connection is correct, then I think replacing the transistor should solve the problem.
Sir work nahi kar raha
Yeh bilkul work karega bhaiya..
Poora connections check kar dhijiye..aur battery jaldi se kadham ho jayega...so please check whether battery is not discharged. Or connect a higher capacity battery..
Also, only CFL bulb will work. LED bulb will not work. Bring CFL bulb near the coil in different orientations. It may not light up in the first attempt. Try many times and Bulb will light up..
Not working
Hi friend. It is a working project only. But it is a bit difficult to make it work in the first attempt itself. You have to take care of many things.
1. You have to use CFL bulb only.
2. The battery gets discharged very fast. So use a high capacity battery with at least 9-12 volts.
3. The CFL bulb has to be brought near the coil in different orientations. During initial attempts, the bulb may not light up. But at one particular time, it will light up. This was my experience.
