Q.

Rectifiers are used to convert -

A. Direct current to Alternating current
B. Alternating current to Direct current
C. high voltage to low voltage
D. low voltage to high voltage
Answer» B. Alternating current to Direct current
Explanation: Converting DC power from one voltage to another is much more complicated. One method of DC-to-DC conversion first converts power to AC (using a device called an inverter), then uses a transformer to change the voltage, and finally rectifies power back to DC.
