An increase of line voltage into a power supply usually produces
A)a decrease in efficiency.
B)a decrease in load resistance.
C)an increase in load voltage.
D)less power dissipation in the rectifier diodes.

Question

Quizplus · Accepted Answer

An increase in line voltage into a power supply typically results in an increase in load voltage, assuming the power supply does not have a perfect voltage regulation system. This is because the output voltage of many power supplies is directly related to the input line voltage, especially in simpler or unregulated designs.
