Resistor-inductor are connected in series between terminals

Reference no: EM13650101

When a resistor is connected across the terminals of an acgenerator (112 V) that has a fixed frequency, there is a current of0.500 A in the resistor. When an inductor is connected across theterminals of this same generator, there is a current of 0.400 A inthe inductor. When both the resistor and the inductor are connected in series between the terminals of this generator, what is a) theimpedance of the series combination? b) the phase angle between the current and the voltage of the generator?
