Physics - Semiconductors Question with Solution | TestHub

The alternating current (a.c.) voltage is first applied to a diode rectifier, which converts the a.c. into pulsating direct current (d.c.).

The pulsating d.c. output is then passed through a filter circuit to remove the a.c. ripples and provide a smoother d.c. voltage.

Finally, the output from the filter is fed to a voltage regulator to obtain a constant, steady d.c. voltage that is independent of load variations.

Therefore, the correct order of operation is diode rectifier, filter, voltage regulator.

Answer: diode rectifier, filter, voltage regulator.
