What is the primary function of a voltage regulator in a d.c. power supply?
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?
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?
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.
