The basic condition for a transistor amplifier circuit is:
Correct answer: A. The base-emitter junction should be forward biased
- A. The base-emitter junction should be forward biased
- B. The base-emitter junction should be reverse biased
- C. The base-colector junction should be forward biased
- D. None of these
Explanation
The transistor will function as an amplifier by increasing the intensity of a weak signal. There will be three terminals on the transistor: base, collector, and emitter. The transistor's emitter and base will be forward biassed, but the collector base area is reverse biassed.

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.
