Homework Statement
Is the resistance equal to V/I at any point, or is it the gradient at that point? And Why?
Homework Equations
The Attempt at a Solution
shouldn't it be the gradient? because it is change in V over change in I?
Thanks~
Yes, it's the gradient. But for ohmic materials (linear resistances), the gradient is same as V/I.shouldn't it be the gradient? because it is change in V over change in I?
Yes =) Thanks for making it clearYes, it's the gradient. But for ohmic materials (linear resistances), the gradient is same as V/I.
Can you say why?
