The capacitive reactance in an RLC circuit is determined to be 31 when the inductive reactance is 16 . (a) Is the generator frequency

The capacitive reactance in an RLC circuit is determined to be 31 Ω when the inductive reactance is 16 Ω.

(a) Is the generator frequency v higher or lower than the natural frequency v0?

(b) Is the phase angle f positive or negative?

(c) Calculate the phase angle f if R = 12 Ω.
