DC Power Supply and Clipper Circuit Quiz

What is the primary function of a transformer in a DC power supply?

• Convert AC to DC

• Step up or step down the voltage

• Stabilize voltage output

• Filter out noise

Which of the following circuits is responsible for converting AC to DC?

• Transformer

• Rectifier

• Filter

• Voltage Regulator

What type of rectifier allows both halves of an AC waveform to pass through?

• Half-wave rectifier

• Full-wave rectifier

• Clipper circuit

• Voltage regulator

In a power supply, what is the role of the filter?

• Convert AC to DC

• Step down voltage

• Remove fluctuations in the DC output

• Provide protection against overvoltage

Which component is typically used in a voltage regulator to maintain a constant DC output?

• Diode

• Zener diode

• Capacitor

• Transformer

Which part of a DC power supply helps smooth the rectified waveform into a steady DC signal?

• Transformer

• Rectifier

• Filter (Capacitor)

• Voltage Regulator

A clipper circuit is designed to:

• Increase the amplitude of an input signal

• Limit the voltage output at a specific level

• Convert DC to AC

• Step up the voltage

In a positive clipper circuit, which part of the waveform is clipped?

• Negative half-cycle

• Positive half-cycle

• Both positive and negative half-cycles

• Neither; it passes the full waveform

What would be the output waveform of a diode clipper circuit if the input is a sinusoidal AC signal?

• A fully rectified DC signal

• A sinusoidal waveform with portions cut off

• A square waveform

• A smooth DC signal

Which of the following statements is true about a Zener diode in a voltage regulator circuit?

• It conducts current in both forward and reverse directions.

• It allows current to flow only in the forward direction.

• It maintains a stable output voltage when reverse-biased.

• It steps up the voltage.
