What is the approximate hybrid parameter current gain of a CE amplifier?

(a) -hfe

(b) hfe

(c) -hfc

(d) hfc

This question was posed to me in an online quiz.

The doubt is from Approximate Hybrid Model and its use in CE, CB, CC in chapter Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Best answer
Correct choice is (a) -hfe

Explanation: The current gain of a common emitter (CE) amplifier can be expressed in terms of approximate hybrid parameters. The current gain hfe is the forward transfer characteristics and is used to calculate the current gain in common emitter amplifiers.
