A coil of inductance 0.50 H and resistance 100 ohm is connected to a high frequency supply (240 V, 10 kHz). (a) Obtain the maximum current in the coil. (b) what is the time lag between voltage maximum and the current maximum. Hence, explain the statement that at very high frequency, an inductor in a circuit nearly amounts to an open circuit. How does an inductor behave in a dc circuit after the steady state?
