Question

Which of the following is an inference made from the linear analysis of a transistor circuit taking source resistance into account?

(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

I had been asked this question in an internship interview.

I'd like to ask this question from Transistor Amplifier Response, Taking Source Resistance into Account in chapter High Frequency Transistor of Electronic Devices & Circuits

Answer 1

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

To explain: While performing the linear analysis of a transistor circuit taking source resistance into account 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.
