Question

Consider the circuit shown below. Find the thevenin’s resistance between terminals A and B.

(a) 1

(b) 2

(c) 1.7

(d) 2.7

I had been asked this question by my college director while I was bunking the class.

Query is from Thevenin’s Theorem in section Useful Theorems in Circuit Analysis of Network Theory

Answer 1

The correct choice is (c) 1.7

The explanation: The resistance into the open circuit terminals is equal to the thevenin’s resistance => Rth = (12×2)/14 = 1.71Ω.
