Response to the following problem :
a. Plot power versus current for a 100-Ω resistor. Use a power scale from 0 to 1 W and a current scale from 0 to 100 mA with divisions of 0.1 W and 10 mA, respectively.
b. Is the curve linear or nonlinear?
c. Using the resulting plot, determine the current at a power level of 500 mW.
