Question

Quizplus · Accepted Answer

A voltage regulator maintains a constant voltage level for AC or DC electrical energy.

Answer: H
 A power converter can also maintain a constant voltage level for AC or DC electrical energy.

Answer: F
 An inverter converts DC to AC, but could also regulate voltage. However, it is not specifically designed for voltage regulation like a voltage regulator or power converter.

Incorrect matches:
A)airflow - relates to the movement of air, not voltage regulation
B)alternating current (AC) - AC can be regulated by a voltage regulator or power converter, but AC itself is not a device that maintains constant voltage
C)collision domain - relates to networking, not voltage regulation
E) FCS (frame check sequence) - relates to networking, not voltage regulation
G)NAS (Network attached storage) - relates to data storage, not voltage regulation
I)rack unit (RU) - relates to the sizing of network equipment, not voltage regulation.
