B) when the noninverting input is greater than the inverting input.
C) when the supply voltage is positive.
D) when the supply voltage is negative.

Question

Quizplus · Accepted Answer

The output of a comparator circuit is negative when the inverting input is greater than the noninverting input. This is because the output of a comparator is determined solely by the relative magnitudes of the inputs. If the inverting input is greater than the noninverting input, the output will be negative, and vice versa. The supply voltage does not have a direct effect on the polarity of the output.
