5 Questions
What is the primary function of a voltage regulator in a d.c. power supply?
To remove ripples from the output and keep the output voltage constant.
Why is a voltage regulator necessary in a d.c. power supply?
To keep the output voltage constant and ripple-free despite changes in the load and input line voltage.
What would happen if a d.c. power supply does not have a voltage regulator?
The output voltage would be noisy and would vary with changes in the load and input line voltage.
What is the main characteristic of a d.c. power supply with a voltage regulator?
Smooth, constant, and ripple-free output voltage.
Why is a voltage regulator necessary to provide a constant output voltage?
To ensure that the output voltage remains constant despite changes in the load and input line voltage.
This quiz covers the need and working of switch mode power supply, including block diagrams. It also discusses the importance of voltage regulators in providing constant and smooth DC supply.
