Question

In the figure, the equivalent resistance between the points A and B is

(a) 8 Ω

(b) 6Ω

(c) 2 Ω

(d) 4 Ω

Answer 1

Correct option (b) 6Ω

Explanation:

Since the resistances R₂ and R₃ are in parallel, their equivalent resistance will be R₂₃ = 2Ω 

Now the equivalent circuit will be

There are three resistances in series. Therefore the equivalent resistance will be R_AB = 2 + 2 + 2 =  6Ω.
