Resonance:
Resonance occurs when the inductive and capacitive reactances in a circuit cancel each other out. This results in maximum current flow and a sharp peak in the impedance curve.
Power factor:
Power factor, influenced by impedance and phase shift, represents the efficiency of power transmission. A low power factor indicates inefficient power usage.

Understanding impedance and phase shift in AC capacitor wiring diagrams is crucial for analyzing circuit performance, predicting frequency response, and optimizing power efficiency. These concepts are essential for designing and troubleshooting AC circuits in various applications, ranging from power systems to electronic devices.
