- Impedance of AC circuit and Admittance of AC circuitSHOW THE CIRCUIT USING ANY SOFTWARE OR YOU CAN DRAW IT MANUAALYY thNAKSSarrow_forwardWhen a resistor is connected across the terminals of an ac generator (117 V) that has a fixed frequency, there is a current of 0.332 A in the resistor. When an inductor is connected across the terminals of the same generator, there is a current of 0.365 A in the inductor. When both the resistor and the inductor are connected in series between the terminals of this generator, what is (a) the impedance of the series combination and (b) the phase angle between the current and the voltage of the generator?
