An alternating current source is applied across a full-wave rectifier. Which of the following will be true regarding the output obtained?
-
A.
The output will be alternating current.
-
B.
The output will be initially direct current and then alternating current.
-
C.
The output will be initially alternating current and then direct current.
-
D.
The output will be pulsating direct current.
Correct Answer:
D. The output will be pulsating direct current.
Explanation:
A full-wave rectifier is an electronic circuit designed to convert an input alternating current (AC) signal into a unidirectional output. Unlike a half-wave rectifier, it processes both the positive and negative halves of the AC cycle, ensuring that current flows through the load in the same direction at all times. Because the magnitude of the voltage still fluctuates over time despite the direction being constant, the resulting output is characterized as pulsating direct current (DC). This ripple can be further smoothed into a steady DC voltage using filters. Therefore, the correct observation for a full-wave rectifier is that the output will be pulsating direct current.
