A. direct current to alternating current B. alternating to direct current C. high voltage to low voltage D. low voltage to high voltage
Correct Answer: B
Explanation
Rectifiers are primarily used to convert alternating current to direct current. They are applicable inside the power supply of virtually all electronic equipment. A rectifier periodically reverses the direction of alternating current \((A C)\) to direct current \((D C)\) which flows in one direction.
