I assume V = voltage, is R current?
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:
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
