When a resistor is connected across the terminals of an acgenerator (101 V) that has a fixedfrequency, there is a current of 0.550 A in the resistor. When an inductor isconnected across the terminals of this same generator, there is acurrent of 0.420 A in theinductor. When both the resistor and the inductor are connected inseries between the terminals of this generator, calculate thefollowing.a) the impedance of the series combinationb) the phase angle between the current and the voltage of the generator.
