I think all of that is wrong.

Is there ecf on any of that? And why cant we multiple length by gradient

Yep, definitely.

Not sure what you mean. It's not necessarily a graph that goes through the origin.

hey the V2 against V2-V1 graph for which I drew a sketch, I passed thorugh he orgin cause c=0.
What did you write for the last to points in that question? for accuracy and precaution?

Yes, that's correct (but not necessary).

Accuracy: letting the capacitor charge up fully

Precaution: checking the orientation of the capacitor in order to avoid overheating.

I wrote the same precaution (connecting the capacitor to the correct terminals) but I wrote repeat and find mean for accuracy... It might be wrong cause you don't repeat for circuits normally as it could heatup right? smh

Guys was the gradient suppose to be positive or negative? I got -ve which cancelled as grad= -p?

Gradient negative, p positive.

Zacken do you think my graph would get any marks? (Look a few posts above)

Gradient negative, p positive.

Oh cool..
Btw what was your value of e?

Yes, it's fine.

1.55.

got 1.51 that looks wring though, anyways the unit for the gradient was K or K^-1

K^(-1).

K^(-1).

Reading to be taken for the capacitor question and the arrangement of the voltmeter?

K^(-1).

ohh... I said it was K.... wasn't it lnA against K^-1

K^(-1).

Shouldn't it be K ??, because then when multiplied by the boltzmann constant it would remove the K^-1 in it thus the final unit would be C instead of Ck^-2

Sorry - yes, I thought you were asking about the unit for the axes. The unit for the gradient is K (although that doesn't matter) as long as you say the unit of p is also K.

Expected boundaries? This paper was filled with 1 markers and made silly mistakes in them :¡ i think it will be lower maybe 28 for an A? What do u guys think?
