Phasors
Save
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.
Types of Phasors
There are two types of phasors: voltage phasors and current phasors. Voltage phasors are used to represent the sinusoidal voltage in a circuit, while current phasors are used to represent the sinusoidal current in a circuit. The voltage phasor is a complex number that has a magnitude equal to the peak voltage of the sinusoidal function and a phase angle equal to the phase angle of the sinusoidal function. The current phasor is a complex number that has a magnitude equal to the peak current of the sinusoidal function and a phase angle equal to the phase angle of the sinusoidal function.
