In the circuit shown, the three voltmeter readings are .

The power factor of the load is

0.45

0.50

0.55

0.60

Explanation:

Since  is the voltage across a resistor so, it will be in same phase as current but voltage across RL load will lead the voltage by power factor angle.

The circuit and phasor diagram are shown below,
