The p-n junction diodes can act as rectifiers because they
- A. conduct current when forward-biasedCorrect
- B. conduct current when reverse-biased
- C. block current when forward-biased
- D. conduct current in both directions
Explanation
A p-n junction diode conducts current when forward-biased and blocks current when reverse-biased, which is why it can act as a rectifier (allowing current in only one direction).
