AP Physics 2
11.4 Electric Power
11.3 Resistance, Resistivity, and Ohm’s Law
An adjustable load resistor of variable resistance \(R\) is connected across an ideal DC voltage source that maintains a constant potential difference \(V_0\). As \(R\) is varied, the current \(I\) through the resistor and the electric power \(P\) dissipated by the resistor both change. Which of the following graphs best represents the power \(P\) dissipated by the load resistor as a function of the current \(I\)?
