Semi conductor diode conducts only when it is:
Correct answer: B. Forward biased
- A. Reverse biased
- B. Forward biased
- C. Not biased
- D. None of these
Explanation
When the diode is forward-biased, the voltage across the diode is in the direction that allows current to flow through it, and the diode conducts. However, when the diode is reverse-biased, the voltage across the diode is in the opposite direction, and the diode does not conduct

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
