- Physics practical on electricity using constantan wire, a voltmeter, and a 2 Ohm standard resistor:
"In this physics practical session, we delve into the fundamentals of electrical circuits using essential components: constantan wire, a precision voltmeter, and a 2 Ohm standard resistor. Watch as we explore the principles of resistance, Ohm's Law, and the behavior of electric currents in a controlled environment. Join us as we measure voltage across the resistor using the voltmeter and demonstrate the practical application of theoretical concepts. Whether you're a student studying physics or simply curious about electricity, this demonstration will provide valuable insights into the world of electrical circuits. Stay tuned for a hands-on learning experience that illuminates the power of physics in action!"
Feel free to adjust the description based on the specific focus or details of your practical session.

😅I hear people comment saying *there's no Potentiometer* .. they forget to realize that 100cm of Constantine wire from point A to B is equivalently equal to a Potentiometer
I.e Potentiometer= 100cm of Constantine wire
Its working principle; V ~ L
V= I L Electric potential ( Slope ) I
= ∆ V / ∆L is equivalent to V/R
V= I R. V/R
Am with you Boss...❤
You're a genius Boss... But students ought to understand the different circuit set-up diagrams(5 to 7) for this particular experiment but there are all pretty much the same...😊
Weldone bro.
I thought since lenght increases with pd, why is pd for 20cm greater than that of other higher lenght on the custantine wire
I tried to explain that but maybe you didn’t get it or I didn’t lay much emphasis on it
Yes that is NECO for you, potentiometer is the 100cm wire that is why joekey is part of the specimen.
Thank you at least someone is thinking like me
Is this experiment better with potentiometer or meter bridge
May Almighty God bless you for all that you do Sir 🙏... Someday this your boy go support you 😅...
You be Boss 👑👏👏
Wow that will be great
Well done sir
But what is the difference between potentiometer and meter bridge relating to their diagram
Just to clear the air..😅😅 my OGA don finish work...
Things to Note as a Physicist!!😅
1. 100cm of Constantine wire= Potentiometer
2. Metre-bridge= Potentiometer
3. Potentiometer x= Metre-bridge
4. The working principle of a Potentiometer is
V ~ L
V = I L ...(I = electric potential)
....🎉🎉Also.......
IR = I L
R ~ L.......
R = s L...... (∆R/∆L = slope; s)
s X Area = electrical resistivity
5. Parameters to evaluate are almost endless 😂 but for the basics, you might be asked to
~ record only L & V. i.e v~L
~evaluate ; V-1, V/R, R/L, log V-1, L-1....
It's probably a
~ graph of V-1 vs L;
evaluate P= s X Vo X R
= Slope x 3 x 2
(Resistance per unit length)
But my 🤔 candid advice for teachers is to run the experiment and evaluate ∆V/∆L = slope📈= electric potential ( i) 🔌and
∆V-1/ ∆L= slope its a constant since you might be asked to record it for evaluation in your report sheet..✅
6. The circuit diagram setup for the experiment come in different forms but there are all the same thing..😊
7. The practical is indeed 💯%™ simple/easy... No stress at all 😬...
Thank you so much. @Teamfcglobal. Your support to this channel is massive.
You see when I read some comments. I just smile. But, how you dey take know all these things. I will do the graph in a separate video. I will plot as you suggested.
@@vindalsacademy You lead ur boy follow Sir 🙏.... I'm honestly great full towards all that you're doing Sir 🙏...
I like the connecting wires used here. please where can i get one
Wow.. this is great and helpful.
Sir, please, is there no way one could manipulate the readings... Ur video on waec(mechanics) saved me because the apparatus wasn't even provided for some of us who were writing on our own.
Greetings,sir. There is no potentiometer in the specimen that were asked to be provided.
Yes you are correct. But, 100cm length of wire (constantan) is the same for me
Did you use the SWG 26 constantan wire or SWG22?
Is there any questions that will follow up after precautions?
Yes of course you may be asked to define p.d, or any questions that involves the experiment you conducted

What is d name of wires he's using for connection
Constantan wire.

Please what is the name of the battery
Hello 👋 I have a question 😢
How about the graph??? 😶
No talk about potentiometer or metre bridge in the specimen sir. I think you need to recheck the neck specimen sent
But, there is jockey and a constantan of 100cm wire.
No mind neco...Know this.. 😅
~100cm of Constantine wire= Potentiometer no matter the electrical circuit set-up...
~ metre-bridge= Potentiometer
~potentiometer not = to metre-bridge
😊😊😊
Please I need help in calculating the refractive index on the physics report sheet
Check my video on playlist Optics.

Sir but meter bridge was not included in the specimen so why are we using it.
A 100cm wire and a jockey and a meter rule. If you combine them you can have a potentiometer
Guys pls what is the name of the other wire used in the experiment apart from Constantine wire. Cause if i know the other wire it will make my experiment easier pls guys reply what is the other wire used is it nichrome or any other wire
Copper wire
Thank you for reaching out. Don’t forget to subscribe, like and share the video to reach other people. And to encourage me to be better.
Thank you sir .but is it only copper wire that can be used for this neco practical.
