Question

We use approximate hybrid models for transistors because they introduce less than 10% error.

(a) True

(b) False

This question was addressed to me during an online exam.

This is a very interesting question from Approximate Hybrid Model and its use in CE, CB, CC in division Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

Right choice is (a) True

Explanation: For the analysis of transistor amplifiers we use approximate hybrid models instead of exact hybrid models. They introduce less than 10% error which can be ignored since hybrid parameters themselves are not steady but vary considerably for the same type of transistor.
