What is the effect of capacitance on wattmeter reading?

A)

aiding the inductance

B)

aiding the capacitance

C)

opposite to that of inductance

D)

opposite to that of resistance

Correct Answer : Option (C) : opposite to that of inductance

Explanation : For lagging power factor of the load, the wattmeter reading is more. As a result, the wattmeter shows a reading opposite to that of the inductance.
