A DC chopper feeds an RLE load. If the value of E is increased by 20%, the current ripple ________
A)increases by 20%
B)decreases by 20%
C)increases only 20%
D)remains the same

Question

Quizplus · Accepted Answer

The current ripple in a DC chopper circuit feeding an RLE load is primarily determined by the inductance (L) and the switching frequency of the chopper, not by the value of E (the voltage). Therefore, changing E does not directly affect the current ripple.
