When a resistor is connected across the terminals of an ac generator (100 V) that has a fixed frequency, there is a current of 0.495 A in the resistor. When an inductor is connected across the terminals of the same generator, there is a current of 0.420 A in the inductor. When both the resistor and inductor are connected in series between the terminals of this generator, what are: (a) the impedance of the series combination and (b) the phase angle between the current and the voltage of the generator?
