• It maintains a constant output voltage

• It controls the input voltage

What are the advantages of using filters in DC power supply?

• To decrease efficiency and introduce fluctuations in the output voltage.

• To increase ripple and noise, and provide an unstable output voltage.

• To reduce ripple and noise, and provide a smooth and stable output voltage.

• To reduce the lifespan of the power supply and cause overheating.

What are the disadvantages of using regulators in DC power supply?

• Regulators are cheap and do not generate heat

• Regulators are not necessary for DC power supply

• Regulators can be expensive and generate heat

• Regulators are not reliable and can cause power fluctuations

How does a capacitor filter work in a DC power supply?

• It amplifies the fluctuations in the DC power supply.

• It has no effect on the DC power supply.

• It converts the DC power supply to AC.

• It smooths out the fluctuations in the DC power supply.

What is the purpose of an inductor filter in a DC power supply?

• To reduce ripple voltage and smooth out the output voltage

• To increase ripple voltage and make the output voltage more unstable

• To generate more noise and interference in the output voltage

• To decrease the efficiency of the power supply and waste energy

Discuss the role of a voltage regulator in maintaining a constant output voltage in a DC power supply.

• To decrease the output voltage in a DC power supply

• To regulate the current in a DC power supply

• To increase the output voltage in a DC power supply

• To maintain a constant output voltage in a DC power supply.

Explain the concept of line regulation in a DC power supply regulator.

• The concept of line regulation is to increase the input voltage to match the output voltage

• Line regulation refers to the ability to maintain a constant input voltage despite changes in the output voltage

• The concept of line regulation in a DC power supply regulator is the ability to maintain a constant output voltage despite changes in the input voltage.

• Line regulation is the process of converting AC power to DC power in a regulator

What is the ripple factor in the context of DC power supply filters?

• A measure of the effectiveness of a DC power supply filter in reducing the ripple voltage.

• The number of ripples per second in the power supply

• The color of the ripple in the power supply

• The temperature at which the power supply operates

How does a shunt regulator differ from a series regulator in a DC power supply?

• The shunt regulator is used for AC power supplies instead of DC.

• The shunt regulator increases the voltage to compensate for fluctuations.

• The shunt regulator diverts excess current to ground.

• The shunt regulator allows all the current to flow through the load.
