Overview
Duty cycle is the percentage of time a signal is active vs total period. Used in PWM motor control, LED dimming, welding equipment ratings, and digital circuits. 50% duty cycle = equal on/off time.

Pro Tips
PWM frequency affects motor smoothness and efficiency.
Welding duty cycle: 60% @ 200A = 6 min weld, 4 min rest.
LED dimming: higher duty cycle = brighter.
Audio PWM requires high frequency (>20kHz) to avoid noise.
