AP Physics C: E&M
11.4 Electric Power
11.3 Resistance, Resistivity, and Ohm’s Law
A simple circuit consists of an ideal DC voltage source delivering a constant potential difference \(V_0\) connected across a variable resistor of resistance \(R\). The resistance \(R\) is increased from an initial non-zero value. Which of the following qualitative descriptions correctly characterizes the graph of the total electrical power \(P\) dissipated by the circuit as a function of resistance \(R\)?
