MHT CET Physics question

Not in JEE Advanced syllabus

A diode converts A.C. voltage into a/an

(A)A.C. voltage with a different peak value
(B)D.C. voltage with a constant value
(C)Bidirectional pulsating voltage with a constant r.m.s. value
(D)Unidirectional pulsating voltage that keeps on dropping in between zero to maximumCorrect

Answer: (D)

Solution

A diode conducts in one direction only, so it converts a.c. into a unidirectional pulsating voltage that varies between zero and the maximum;
