What is the basic primary function of a semiconductor diode?
What is the basic primary function of a semiconductor diode?
Multiple Choice Options
- A
amplification
- B✓ Correct Option
rectification
- C
modulation
- D
oscillation
Detailed Technical Solution & Explanation
The defining property of a semiconductor p-n junction diode is unidirectional conductivity (conducting with low resistance when forward-biased, blocking with high resistance when reverse-biased). This allows it to convert alternating current (AC) into pulsating direct current (DC), a process called rectification.
Option Analysis:
•
Option A (amplification): Incorrect. Diodes are passive two-terminal devices and cannot provide power or signal amplification.
•
Option B (rectification): Correct. Converting AC to DC via one-way conduction is the primary function of a diode.
•
Option C (modulation): Incorrect. Modulation is typically performed by non-linear mixers or active multiplier circuits.
•
Option D (oscillation): Incorrect. Sustained oscillation requires an active device with positive feedback gain.
