The electrical circuit used to get smooth `dc` output from a rectifier circuit is called

Options

A. an oscillator circuit
B. a filter circuit
C. an amplifier circuit
D. a logic gate

Answer

B

Explanation

To get smooth d.c. output from a rectifier circuit (both half wave or full wave), a filter circuit is used. The output contains both a.c. and d.c. components. The filter circuit removes the a.c. component.
