Phasors

May 1, 2024 3 minute read

Phasors are a mathematical tool used to represent sinusoidal functions, making it easier to analyze and solve AC circuit problems. They are a complex number that has both a magnitude and a phase angle. The magnitude of a phasor represents the amplitude of the sinusoidal function, while the phase angle represents the phase shift of the function relative to a reference point. When analyzing AC circuits, sinusoidal functions are used to represent the voltage and current. These sinusoidal functions can be represented using complex numbers, and these complex numbers can be manipulated to analyze the circuit using basic algebraic operations.
