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. |
