Question

We use simplified CE hybrid models to obtain approximate values.

(a) True

(b) False

I have been asked this question during an internship interview.

My question is taken from Simplified CE Hybrid Model topic in section Low Frequency Transistor Amplifier Circuit of Electronic Devices & Circuits

Answer 1

Right option is (a) True

To explain I would say: It is more practical to calculate the approximate values of voltage and current gains instead of computing the exact values of a common emitter amplifier circuit. We use a simplified common emitter hybrid model to obtain these approximate values without reducing the accuracy.
