If Y = 20 mS, then Z = 20.

In a series RL circuit, a power factor of 0.5 results in less energy conversion to heat than does a power factor of 0.6.

If a 7.5 k resistance is connected to a 10 k inductive reactance in a series RL circuit, then the impedance equals 12.5 k .

Phase angle is the difference in phase between the applied voltage (VS) and the circuit current (I_T).

The circuit in the given circuit is a low-pass filter.
