Question:

A professor gave the following quiz to his students:
Look at Figure P12-42. Each curve represents the voltage across an individual element in a series $R L C$ circuit. Identify which curve belongs to which element, namely, $R, L, C$, or $V_{1}$. Then explain how there can be two voltages greater than $1(\mathrm{odB}$ when the input $V_{1}$ is at $\mathrm{O} \mathrm{dB}$ ?
