What is the purpose of filter at the output side of diode bridge rectifier?

a: It reduces the ripple content in the output voltage only and decreases dc-load power. Explanation

Explanation

b: It reduces the ripple content in the output voltage, output current and increases the dc-load power. Explanation

Explanation

c: There will be no change in any of the parameters. Explanation

Explanation

d: The ripple content in the output dc-load voltage increases. Explanation

Explanation

2. What will happen if one of the diodes in an uncontrolled diode bridge rectifier is permanently open?

a: Nothing will change it works as before. Explanation

Explanation

b: It works as uncontrolled half wave rectifier. Explanation

Explanation

c: Gives no dc output voltage. Explanation

Explanation

d: Gives ac output voltage. Explanation

Explanation
