In a half-wave rectifier, the diode conducts during:
Correct answer: A. One half of the input cycle
- A. One half of the input cycle
- B. A portion of the positive half of the input cycle
- C. A portion of the negative half of the input cycle
- D. Both halves of the input cycles
Explanation
The answer is A since the positioning of the diode would ultimately decide whether the positive half is allowed to flow or the negative half. Since we aren't aware of the position/direction of the diode, we would go with A.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
