1. The problem statement, all variables and given/known data Hello, in physics the other day we sat a test which asked up to measure current and resistance of different resistors in a circuit. After collecting the data and plotting the graph for current vs resistance and coming up with a curve indicating an exponential relationship, we were then asked to manipulate the data to produce a graph with a straight line relationship between I and R. 2. Relevant equations V=IR 3. The attempt at a solution Now looking at the equation, it's obvious there is no option to square either side like you might for a distance/time graph. But that doesn't get me any closer to the end result. I thought about plotting R=V/I, but that doesn't do anything productive seen as though it was all measured at 6 volts, and, well, plotting a constant wont give me the proportional relationship I require, my teacher suggested I focus on the equation, but I really don't see anything else I can do? Any help would be very much appreciated, thanks for your time.
