Phasor diagrams are graphical representations used to visualize and analyze alternating current (AC) circuits by representing sinusoidal voltages and currents as vectors, or phasors. Each phasor is depicted as an arrow in the complex plane, where the length represents the amplitude and the angle indicates the phase relative to a reference. This method simplifies calculations of AC quantities, making it easier to understand relationships between different circuit elements, especially in RLC circuits.
congrats on reading the definition of phasor diagrams. now let's actually learn it.
