sir namaskar i am from nepal m big fan of you sir.sir please inverter ac outdoor unit kaa high or low voltage protection problem maa solve kese karey ek video banadijiya na essy sabi technician ko help melega
Sir please make video on secondary winding of power transformer is kept open for a long time what will happen (Power transformer not a current transformer)
instead of freewheeling diode, if we put a capacitor, will it charge? this way we can harness the collapsing field energy aka back spike or flyback and utilize it for external work?
Due to inductor in load. But if you are talking about inductor of relay coil and non inductor load Then ssr will help. No diode required. I made many videos with different circuit condition.
@@GKAgrawal2 actually my ebike motor kit has no switch so using relay but controller is packed up as I did not put diaod side of relay by mistake...now new contraller I will use but with SSR...I think 3 phase motor controller is non inductive load, right?
Sir Mera ek saawal hai. transformer 5 Saal se Chalo hai.mujhe abhi 2 Saal ke Liye baand Karna hai.isse transformer ko koi nukshan to nahi Hoga? Transformer 34.5kv ka hai.output 480 hai.
Transformer ko Koi nuksan nahi hoga lekin phir se chalu karne ke liye aapko uska transformer oil filter or change karna padega, Agar Agrawal sir iska Answer deta hai to aap jarur padna.
Depends upon use, this is just example to explain problem and use of diode. if inductor is there like in this circuit, then freewheeling diode required.
@@GKAgrawal2 sir one more question if not inductor in a circuit and opened the switch spark coming also, why? While no inductor and no energy need to go some where so no need to spark but also sparking
That is due to the electrical break down of gases between switch contacts during switch opening. This phenomenon is used for arc welding of iron rod with low voltage circuit.
Wah sir.. What a great explanation. Bilkul hi feel aa gya ❤
Bahut bahut dhanya waab guru jii , the best teacher of youtube
Nice nice explanation. Guru ji 👌🙏
Sir you are great teacher. I am unlucky that I didn't get a teacher like you during my engineering time.
All the best Sir👍💯
Thank you Sir. Ek bari mei samajh aa gya itna achche se samjhaya aapne.
Watch working of freewheeling diode in Hindi
wah sir ji, sab samjh me aagaya
You are best teacher ❤
Free wheeling diode working explained very well
Wah sir great explanation 🎉
Ati uttam gurudev
बहुत बहुत धन्यवाद गुरूजी 🙏🙏
Excellent sir ji
👌
धन्यवाद गुरुजी।।🙏✨
bahot badiya
nice explained sir
Jay hind sir, your are great teacher
Jai Hind
Very very good sir😍
Mai abhibsearch hi kar rha tha ki just
Aapka uploaded notification aaya
Yeh Pura video dekho
Dhanyabaad guruji 🙏❤️

Thank you very much sir
Legend sir..
Thank you sir
Nice explan
Thank you sir🙏 great explain 👍

Great Explanation.
Thank you so much sir 🙏
instead of freewheeling diode, if we put a capacitor, will it charge?

No, capacitor will charge no doubt, but other components may damage. Further L and C may resonance.
Thank u sir 🙏
Sir, Can you post a video explaining the working of Variable Frequency Drive in Detail.
There are few videos on VFD already.
Nice👍👍 sir,, sir ji jo voltage increases hoga wo DC voltage hoga ya ac voltage hoga
DC, as circuit is dc
Very good
Thanks 👍
Hello sir
Earth fault and earth likage ke liye RCCB sahi rahega
please sir , can you explain shielding system in substation
Sir, please explain the working of smps, its components and complete electronic circuit in detail.
Made already one video on SMPS.
Thanx sir

Sir नमस्ते
Namaste sir ,kya kisi circuit m mosfet ki jagah transistor laga sakte hai
kuch ckt mey laga saktey hai, kuch circuit mey nahi.
Dear sir l*di/dt values how much? Please
sir if I use SSR can reverse current issue solve..without diode
No, energy stored in the inductor has to be dissipated some where, or to be used somewhere.
@@GKAgrawal2 SSR (solid state relay ) uses no contact system as there is no coild inside so how will the same damage the load
Due to inductor in load. But if you are talking about inductor of relay coil and non inductor load Then ssr will help. No diode required.
I made many videos with different circuit condition.
@@GKAgrawal2 actually my ebike motor kit has no switch so using relay but controller is packed up as I did not put diaod side of relay by mistake...now new contraller I will use but with SSR...I think 3 phase motor controller is non inductive load, right?
Motors have coils inside. And coils has some equivalent inductor.
Inverter circuit me MOFET K Across bhi freewheel diode hota hai uska kya use hai
Mera video IGBT based rectifier dekho.

oil filter or change karna padega, Agar Agrawal sir iska Answer deta hai to aap jarur padna.
One question : Can a transformer which works on 50 Hz supply , be used on 60 Hz supply ?
Yes, losses may be more
Due to core losses depends on Frequency then losses will more for +10Hz supply.
Dear sir
Why need Inductor in this circuit ?
Depends upon use, this is just example to explain problem and use of diode. if inductor is there like in this circuit, then freewheeling diode required.
@@GKAgrawal2 sir one more question if not inductor in a circuit and opened the switch spark coming also, why?

Dear sir
If circuit is ac how can control?
Triac are used in place of switch in the critical applications. However, I told in the video that problem is less in the AC circuit.
👌👌👌👍
A.c .me daod k liye kya लगाएंगे
Enlightened! Thanks!
Guru ji mere 7 subject back ho gayi aur UA-cam par pura syllabus bhi nahi mil raha hai kya kru pls help me
Book se Padhne kaa try Karo.
Guru ji nk book se jyada samaj nahi ata hai... Aur mai 2019 batch se hu
Mera 2 videos dekho.
1 - how to become topper.
2- 4 study tips for Science math looks easy.
Aap kun book padti hai
Sir code number ( name of this diodes
DI DT Kay hai
Rate of change of current, it shows , how fast current is increasing.
😂😂😂
Bataooo
Thanks Sirji
