Duty cycle = t(on)/total time.
o/p voltage = v(input)*dutyt cycle.
Now if duty cycle is low then current would flow for v(input). So option A is correct.
o/p voltage = v(input)*dutyt cycle.
Now if duty cycle is low then current would flow for v(input). So option A is correct.

I think assertion should be "If the duty cycle of the chopper is low the current would become discontinuous".

" If the duty cycle of the chopper is low the current would not become discontinuous".
"If the duty cycle is low, current may become discontinuous. ".
Are these two statements not contradicting? Anyone answer me.
