Question

Apparent power is also known virtual power.

(a) True

(b) False

The question was asked in class test.

This question is from Power in AC Circuit : The Power Factor in section Alternating Current of Physics – Class 12

Answer 1

Correct option is (a) True

The explanation is: Yes, apparent power is also known as virtual power. Apparent power is defined as the product of virtual voltage (Vrms) and virtual current (Irms). It is the combination of reactive power and true power and is measured in the unit of volt-amps (VA).

Pv=VrmsIrms=\(\frac {V_o I_o}{2}\)
