Solution
Correct Answer:
Pulsating DC
A rectifier is a device that converts Alternating Current (AC) which reverses direction, to Direct Current (DC) which flows in only one direction.
- A full-wave rectifier uses both cycles of the AC input to produce a unidirectional output.
- However, the output is not a steady constant value; it varies with time in a series of peaks and valleys (sinusoidal pulses).
- This results in pulsating DC. To get a smooth, steady DC voltage, 'filter' circuits (using capacitors/inductors) are needed.
This medium difficulty physics question is from the chapter semiconductor electronics, covering the topic of rectifier. It appeared in the 2025 exam.
