Question

What bias conditions must be present for the normal operation of a transistor amplifier?

A. The emitter-base junction must be forward biased, and the collector-base junction must be reverse biased.
B. Both junctions must be forward biased.
C. The emitter-base junction must be reverse biased, and the collector-base junction must be forward biased.
D. Both junctions must be reverse biased.

Answer 1

The condition that must be present for the normal operation of a transistor amplifier is the emitter-base junction must be reverse biased, and the collector-base junction must be forward biased. The answer is letter C. It should not drive the transistor either into saturation or into cu – off, resulting in one will deem transistors to be inefficient
