Quiz 1 ( Design Linear DC Power Supply)

What is the main function of a rectifier?

• Convert AC to DC

• Convert DC to AC

• Amplify signals

• Regulate voltage

What is the difference between a half-wave rectifier and a full-wave rectifier?

• There is no difference between a half-wave rectifier and a full-wave rectifier

• The full-wave rectifier only allows one half of the AC input signal to pass through

• The half-wave rectifier only allows one half of the AC input signal to pass through, while the full-wave rectifier allows both halves of the AC input signal to pass through.

• The half-wave rectifier allows both halves of the AC input signal to pass through

Explain the working principle of a bridge rectifier.

• It uses a configuration of four diodes to convert AC to DC

• It uses a configuration of three diodes to convert AC to DC

• It uses a configuration of five diodes to convert AC to DC
