🤓 Based on our data, we think this question is relevant for Professor Costantino's class at PSU.

Solution: A series RLC circuit with L = 25 mH, C = 0.8 μF and R = 7Ω is driven by a generator with a maximum emf of 12V and a variable angular frequency ω. At resonance, the current a) leads the generator voltage by 90°. b) lags the generator voltage by 90°. c) is in phase with the generator voltage.

Problem

A series RLC circuit with L = 25 mH, C = 0.8 μF and R = 7Ω is driven by a generator with a maximum emf of 12V and a variable angular frequency ω. At resonance, the current

a) leads the generator voltage by 90°.

b) lags the generator voltage by 90°.

c) is in phase with the generator voltage.
