Gradients?
I have to find the gradients from the information it gives me, it has an example but I have no idea how it gets from there to the answer, the example is:
Equation: R=V/I
Then it says: x axis: voltage
y axis: current
Then it gives the answer: Gradient = 1/R
But I don't understand how to get the answer from the information it gives me?
Any help would be aprecated :)

Re: Gradients?
I assume V = voltage, is R current?

Re: Gradients?
I is current because R is resistance but I don't understand how to get the gradient from it? :)

Re: Gradients?
Well $\displaystyle R = \frac{V}{I} \implies I = \frac{V}{R} $ which means I and V have a linear relationship. The gradient of this relationship is $\displaystyle \frac{1}{R}$
