A 100 micro F capacitor in series with a 40 ohm resistance is connected to a 110 V, 12 kHz supply? (a) What is the maximum current in the circuit? (b) What is time lag between the current maximum and voltage maximum? Hence, explain the statement that a capacitor is a conductor at very high frequencies. Compare this behaviour with that of a capacitor in a dc circuit after the steady state.
