The value of a AC sine wave at any instant can be represented by: A) a phasor whose angle and magnitude are representative of the AC signal. B) the formula V_i=V_p* sin θ C) a graph of the voltage or current vs. the angular measurement. D) all of these.

Question

Quizplus · Accepted Answer

All of the choices are correct in representing the value of an AC sine wave. A phasor can be used to represent the magnitude and phase angle of the AC signal. The equation V_i=V_p* sin θ can be used to calculate the voltage or current at a given angle. A graph of the voltage or current vs. the angular measurement can also be used to represent the AC sine wave.
