Phasor notation is a mathematical representation of sinusoidal functions using complex numbers to simplify the analysis of alternating current (AC) circuits. It allows engineers to convert time-varying voltages and currents into a steady-state form, making calculations easier by focusing on magnitude and phase angle rather than the changing nature of sinusoidal signals. This approach is particularly useful in nodal analysis, where relationships between circuit elements can be expressed more clearly and efficiently.
congrats on reading the definition of phasor notation. now let's actually learn it.
