What is primary function of a rectifier?
-
A.
To regulate output signal
-
B.
To amplify the input signal
-
C.
To convert AC signal in DC signal
-
D.
To filter out unwanted frequencies
Correct Answer:
C. To convert AC signal in DC signal
Explanation:
A rectifier is an electronic device specifically designed to convert alternating current (AC), which periodically reverses direction, into direct current (DC), which flows in a single direction. While components like amplifiers increase signal strength and filters remove specific frequencies, the fundamental role of a rectifier is this conversion process, known as rectification. By allowing current to pass through in only one direction, it ensures a stable and unidirectional output suitable for powering most electronic appliances. Therefore, the correct option is C.
