Question

How many known variables do we need to perform a linear analysis of a transistor circuit?

(a) 3

(b) 5

(c) 6

(d) 4

This question was posed to me in class test.

My question is from Linear Analysis of a Transistor Circuit topic in division Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

The correct answer is (d) 4

The best I can explain: There are a total of 6 variables in a transistor circuit. A transistor is a three-terminal device with each terminal having current and voltage measurements. We require any four variables to determine the other two variables of a transistor circuit.
