👉 The concept of a phasor, also known as an electric field vector or a complex number in physics, is a fundamental unit used to represent signals and systems. Phasors are important because they allow for the manipulation of complex numbers, which can be particularly useful in signal processing and control theory. In electrical engineering, phasors are often used to represent voltage, current, impedance, power, and other quantities that are commonly encountered in circuits or electronic components. They form a fundamental part of
