A crystal diode is used as______________?
Correct answer: B. a rectifier
- A. an amplifier
- B. a rectifier
- C. an oscillator
- D. a voltage regulator
Explanation
A diode conducts mainly in one direction, allowing it to convert alternating current into pulsating direct current in a rectifier. Amplifiers and oscillators require active devices, while voltage regulation is a specialized diode application.
