The simplest type of rectification known as half wave rectification is obtained by____________________?
Correct answer: C. suppressing half wave of A.C supply by using diode
- A. using a transistor
- B. suppressing the harmonics in A.C voltage
- C. suppressing half wave of A.C supply by using diode
- D. using a Coolidge tube
Explanation
A diode conducts readily in forward bias and blocks current in reverse bias, so placing it in an AC circuit allows one half cycle to pass while suppressing the other. This one-sided conversion is half-wave rectification. The likely mistake is choosing a transistor, which can control current but is not the basic device used for this rectification process.

About Rectification
Rectification converts alternating current into unidirectional current using semiconductor diodes. The content includes half wave and full wave rectifiers, bridge circuits, output waveforms, ripple and smoothing with capacitors, with the difference between rectification and voltage regulation kept clear.
