In ac circuits the projection of phasor gives
WebJun 26, 2016 · For a general AC circuit, the phasor is a way of representing a sinusoidally (sine wave) varying input signal. The phasor has fixed length in phasor space, and rotates counterclockwise at a set frequency. The actual voltage or current is the real component of the phasor, or the projection of the phasor onto the real axis. We use the phasor as a ...
