Question

The magnitude of a phasor representing an AC voltage signifies ______.

विकल्प

• The RMS value of the voltage

• The average value of the voltage

• The amplitude (peak value) of the oscillating voltage

• The instantaneous value of the voltage

Answer 1

The magnitude of a phasor representing an AC voltage signifies the amplitude (peak value) of the oscillating voltage.

Explanation:

The magnitude of a phasor represents the amplitude or peak value v_m​ (or i_m​ for current) of the oscillating quantity. The actual instantaneous value is obtained from the vertical projection of the phasor.
