Define Phasor and Phase angle. Answer : ### Phasor: A **phasor** is a complex number that represents the magnitude and phase of a sinusoidal waveform (usually a voltage or current). Instead of dealing with the waveform in time ... (advanced). So, the phase angle helps describe the timing difference between different sinusoidal signals....
