Question

A circuit containing a 80 mH inductor and a 60 µF capacitor in series is connected to a 230 V, 50 Hz supply. The resistance of the circuit is negligible.
(a) Obtain the current amplitude and ran values.
(b) Obtain the rms values of potential drops across each element.
(c) What is the average power transferred to the inductor?
(d) What is the average power transferred to the capacitor?

Answer 1

L = 80mH = 80 × 10^-3H
C = 60pF = 60 x 10^-6F
E = 230 V
F = 50 Hz
