A PN junction conducts only when it is:
Correct answer: B. Forward biased
- A. Reverse biased
- B. Forward biased
- C. Neither reverse nor forward biased
- D. All of these
Explanation
A PN junction conducts current only when it's forward biased. When a PN junction is forward biased, meaning the positive terminal of the voltage source is connected to the P-type semiconductor and the negative terminal is connected to the N-type semiconductor, it allows current to flow through it.

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.
