B) Compulsory
C) Pulse width
D) Deep

Question

Quizplus · Accepted Answer

Pulse width modulation (PWM) is a technique used to regulate the output voltage by varying the time a transistor conducts as compared to the time it is turned off. By adjusting the on-time of the transistor, the average voltage delivered to the load can be controlled. This is commonly used in applications such as motor control, LED dimming, and power electronics.
