AS physics question on resistance graph.

[Peter Check]

http://www.xtremepapers.com/papers/...nd AS Level/Physics (9702)/9702_s10_qp_23.pdf question 6 b, why cant we use the gradient( 1/m is constant so resistance also is constant!)

Using the inverse of the gradient is precisely what they have done in the marking scheme.......the question is out of two marks so you have to explain how to find the inverse of the gradient too...............the marking scheme says using the GRADIENT loses the mark.........so you can use the inverse of the gradient.......hope you understood

yeah thnx a tonne

ur welcome

we cannot use gradient wat so ever in this question remember this for all I-V graphs when ever question says to find out resistance just choose V and I values from the graph and put them in formula V/I ,,,,,,,, use of gradient in these questions is not allowed according to the mark scheme.....
