Q.1
The phase angle (?) of a series RL circuit varies directly with frequency.
Q.2
The power factor indicates how much of the apparent power is reactive power.
Q.3
If a load is purely inductive and the reactive power is 12 VAR, the apparent power is
Q.4
A 140 Ω resistor is in parallel with an inductor having 60 Ω inductive reactance. Both components are across a 12 V ac source. The magnitude of the total impedance is
0 h : 0 m : 1 s
