Question:

Figure P22.29 shows the current-versus-potential-difference graph for a resistor.

a. What is the resistance of this resistor?

b. Suppose the length of the resistor is doubled while keeping its cross section the same. (This requires doubling the amount of material the resistor is made of.) Copy the figure and add to it the current-versus-potential-difference graph for the longer resistor.image text in transcribed
