When only a resistor is connected across the terminals of an ac generator (117 V) that has a fixed frequency, there is a current of 0.490 A in the resistor. When only an inductor is connected across the terminals of this same generator, there is a current of 0.432 A in the inductor. When both the resistor and the inductor are connected in series between the terminals of this generator, calculate the following.
(a) the impedance of the series combination
?
(b) the phase angle between the current and the voltage of the generator
