An AC source drives an RLC circuit with a fixed voltage amplitude. If the driving frequency is ω1, the circuit is more capacitive than inductive and the phase angle is -10°. If the driving frequency is ω2, the circuit is more inductive than capacitive and the phase angle is +10°. At what frequency is the largest amount of power delivered to the circuit? (a) It is largest at ω1. (b) It is largest at ω2. (c) The same amount of power is delivered at both frequencies.
