AC (Alternating Current) Analysis

AC (Alternating Current) analysis involves studying how circuits respond when the electrical voltage and current continually change direction and magnitude over time, typically in a sinusoidal pattern. It helps engineers understand how components like resistors, capacitors, and inductors behave under these oscillating signals, affecting things like signal transmission and power delivery. By analyzing AC, we can determine parameters such as impedance, phase shifts, and power flow, which are crucial for designing efficient electrical and electronic systems, including radios, audio equipment, and power grids.
