Obtain the answers to (a) and (b) in given question, if the circuit is connected to a
110V,12kHz supply? Hence, explain the statement that a capacitor is a conductor at very high frequencies. Compare this behavior with that of a capacitor in a dc circuit after the steady-state.
A 100 μF capacitor in series with a 40Ω resistance is connected to a 110V,60Hz supply. (a) What is the maximum current in the circuit?
(b) What is the time lag between the current maximum and the voltage maximum?
