hi every1

im in the middle of my gcse physics coursework "how does the resistance of a wire change when you hange the length" and i was wondering how you plot the graph .should i plot both voltage against current and length against resistance or just one of them?

Plot the resistance vs. length graph, should yield a straight line showing resistance is directly proportional to length. There's not much point in plotting the other one, if you're investigating how the resistance depends on the length, as it doesn't really tell you much.

Plot the graph of PD with Current first, use the proportion to show its resistance. Then plot the graph of different lengths against Current
