Q. The voltage π£(π‘) across the terminals a and b as shown in the figure, is a sinusoidal voltage having a frequency π = 100 radian/s. When the inductor current π(π‘) is in phase with the voltage π£(π‘), the magnitude of the impedance Z (in Ξ©) seen between the terminals a and b is (up to 2 decimal places).
Ans: 50
