Question

Which of the following is an inference made from the linear analysis of a transistor circuit?

(a) 99% of the collector current flows to the emitter

(b) 99% of the emitter current flows to the collector

(c) 0.99% of the collector current flows to the emitter

(d) 0.99% of the emitter current flows to the collector

The question was asked at a job interview.

I'd like to ask this question from Linear Analysis of a Transistor Circuit topic in chapter Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

The correct answer is (a) 99% of the collector current flows to the emitter

Explanation: While performing the linear analysis of a transistor circuit we observe that 99% of the collector current flows to the emitter. Current always flows from the collector to the emitter and not the other way around since the emitter terminal is usually grounded.
