Which circuit is commonly used to convert AC electricity into DC electricity by using both halves of the input waveform?

• A. Half-wave Rectifier
• B. Germanium/Silicon
• C. Full-wave Rectifier
• D. Output DC voltage

Answer: (C)

A circuit that uses both halves of the input waveform to produce DC is called a full-wave rectifier. It uses diodes arranged so that current is directed through the load in the same direction during both the positive and negative halves of the AC cycle. This effectively flips the negative half so it contributes to the output just like the positive half, doubling the frequency of the ripple and increasing the average output voltage compared with a half-wave rectifier. In practice, this is implemented as a bridge rectifier with four diodes (or a center-tapped transformer with two diodes). The other options aren’t circuits that use both halves: one describes a diode material, and the other describes a result, not a rectifying arrangement.
