Question

An electrical signal can be represented in either Thevenin form or Norton From. However, Thevenin representation is preferred when

(a) The load resistance is very large as compared to the source resistance

(b) The load resistance is very low compared to the source resistance

(c) There is no preferred case.

(d) Both of the cases mentioned are the preferred case

I got this question in final exam.

I'd like to ask this question from Signals in portion Signals and Amplifiers of Electronic Devices & Circuits

Answer 1

Correct answer is (a) The load resistance is very large as compared to the source resistance

For explanation I would say: a is preferred in Thevenin’s case and b in Norton’s case
