👉 A phasor is a mathematical representation of an electrical signal, which represents the complex value of a sinusoidal function over time. Phasors are often used in electronics to represent signals that have varying amplitude and phase values over time, such as alternating current (AC) power or magnetic fields. Phasors can be represented by a vector with both magnitude and phase angles. The magnitude of the phasor represents the total amount of energy present in the signal, while the phase angle indicates the
