What is the basic function of a semiconductor diode?
What is the basic function of a semiconductor diode?
Multiple Choice Options
- A
amplification
- B✓ Correct Option
rectification
- C
modulation
- D
oscillation
Detailed Technical Solution & Explanation
A semiconductor diode conducts current with low resistance when forward-biased and blocks current when reverse-biased. This one-way conduction mechanism is used to convert alternating current (AC) to direct current (DC), known as rectification.
Option Analysis:
•
Option A (amplification): Incorrect. Passive diodes cannot amplify power.
•
Option B (rectification): Correct. Unidirectional conduction rectifies AC to DC.
•
Option C (modulation): Incorrect.
•
Option D (oscillation): Incorrect.
