Question

Why half-wave rectifiers are normally not used in the circuits?

• A. More wastage of power in terms of heat.
• B. It needs a lot of space in the circuit.
• C. It works on very small voltage.
• D. It is very costly.

Answer 1

The correct option is A More wastage of power in terms of heat.

When we use a half-wave rectifier, a significant amount of power/energy gets wasted in terms of heat because only one half of each cycle passes through at a time and the other half cycle gets blocked.

Hence, option $\left(C\right)$ is the correct answer.
