Question

Find the equivalent resistance between terminals A and B in the following circuit.

(a) 3

(b) 3.03

(c) 3.33

(d) 3.63

This question was addressed to me by my college professor while I was bunking the class.

The doubt is from Norton’s Theorem topic in portion Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Correct answer is (c) 3.33

For explanation I would say: The resistance at terminals AB is the parallel combination of the 10Ω resistor and the 5Ω resistor => R = ((10×5))/(10+5) = 3.33Ω.
