(a) 2

(b) 4

(c) 6

(d) 8

I had been asked this question in an interview.

I would like to ask this question from Two-Port Devices and Hybrid Model in chapter Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

Right choice is (b) 4

Explanation: A two – port network has four terminals, two input terminals and two output terminals. Each pair of input or output terminals consist of a current and voltage terminal. In a two – port network, port 1 is usually the input terminal while port 2 is the output terminal.
