A dc voltage source produces a constant load voltage
A) for different load resistances.
B) for equal load resistances only.
C) with zero load resistance.
D) by using alternating current.

Question

Quizplus · Accepted Answer

A DC voltage source is designed to produce a constant voltage regardless of the load resistance. In other words, the load voltage remains constant whether the load resistance is low or high. This is a key advantage of a DC voltage source as it provides a stable output voltage that is essential for electronic devices to function properly. Therefore, the correct choice is A.

B is incorrect because it implies that the DC voltage source can produce a constant load voltage only for equal load resistances, which is not true.

C is incorrect because a zero load resistance will cause the load voltage to be the same as the source voltage, not a constant voltage.

D is incorrect because a DC voltage source produces direct current, not alternating current.
