Thank you Sir, but i think the current for each length of wire has to be the same since the wire and the 2ohm resistor are arranged in series... From the theory resistors in series have the same current
That's true. Because of the time and length of the video. All what you can do when the voltmeter is connected across the series connection is just to add the two resistances to gether and then apply V = IR.
Well done sir.. very helpful. But, i want to knw if the 3.014 ohms/m is generic for the SWG 26 wire... how did they come about the value? Is it fixed for this type of wire since we have others like swg 20, 38 etc ?
The length of Constantine wire is in cm while resistivity per unit length is in metres . I believe they should be in the same si unit probably in cm as the wire length is in cm. Please cross-check your conversion
Hello sir.. Please, I also want to know if the internal resistance in this case can be negligible or is it a must to calculate it while doing the manipulation? Thanks in anticipation 🙏🙏🙏
@AkogwuMoses-cc9qd I think it's good to add it. Here is what you can do. Look for a question on electricity where the emf is 2 or 3 volts. Check the internal resistance given in the question. Use it as the internal resistance of the battery.
@@yousciencelab5307 in Ur own opinion, can we can alsi use a potentiometer to represent the constantan wire .since the potentiometer is a constantan wire as well
@okoroikenna9053 it will be OK. But remember that they asked for a specific tyle of constantan wire. Your potentiometer wire may not be exactly the same as the required wire.

@okoliepromise807 no. It's not necessarily so. Different resistances can be connected in series or parallel
Well Done sir🎉🎉🎉🎉 it's the second case that came out
@@BlossomOladapo-yc7sx yeah.
@@yousciencelab5307 Sir just to confirm the graph we were asked to plot is it positively sloped or negatively sloped
@@BlossomOladapo-yc7sx I didn't plot it. But I think it should be positive
@@yousciencelab5307 ok thanks a lot sir once again I appreciate 😊😊😊😊
@@BlossomOladapo-yc7sx you're always welcome
Brilliant work. One more scenario you did not consider is the voltmeter across both the standard resistor and the constantan wire while in series.
That's true. Because of the time and length of the video.

Sir you are just so amazing Tnks for this
So nice of you

It is calculated using the diameter, leng and resistivity of the wire.

@@chineduigbokwe8580 I believe you saw in the video where I divided L by 100.
Sensitivity must be in ohms per metre.
@@yousciencelab5307 it was divided and clerity were made

@@yousciencelab5307 okay.. thank you very much
I didn't see where u connectedbor used jockey sir
I used a crocodile clip. It serves the same purpose as jockey

How can we get our V°
@@SamuelStephen-gd3py you saw it in the video.
