12–53 Aprofessor gave the following quiz to his students:

Look at Figure P12–53. Each curve represents the voltage across an individual element in a series RLC circuit. Identify which curve belongs to which element, namely, R, L, C, or V1. Then explain how there can be two voltages greater than 1 ð0 dBÞ when the input V1 is at 0 dB?
