The property of a diode that lets it convert alternating voltage is used in a circuit called a:
ARegulator
BRectifier
CResistor
DReflector
Answer & Solution
Correct answer: B. Rectifier
1. A diode conducts in one direction and not the other.
2. That one-way behaviour can turn alternating into direct.
3. This property is used to rectify alternating voltages and the circuit is called a rectifier.
4. So the answer is a rectifier.
