What will be the most suitable combination of three resistors A = 2 Ω, B = 4 Ω, C = 6 Ω so that (22/3)Ω is equivalent resistance of combination? (a) Parallel combination of A and C connected in series with B. (b) Parallel combination of A and B connected in series with C. (c) Series combination of A and C connected in parallel with B. (d) Series combination of B and C connected in parallel with A.

Answer: (b). Try (b): A parallel B gives (2 × 4)/(2 + 4) = 4/3 Ω. In series with C: 4/3 + 6 = 22/3 Ω So the answer is (b).

Combination of Resistors

What will be the most suitable combination of three resistors A = 2 $\Omega$ , B = 4 $\Omega$ , C = 6 $\Omega$ so that $\left(\frac{22}{3}\right)\Omega$ is equivalent resistance of combination?

Show answer and solution

Answer: (b)

Try (b): A parallel B gives $\dfrac{2 \times 4}{2 + 4} = \dfrac{4}{3}\ \Omega$ .
In series with C: $\dfrac{4}{3} + 6 = \dfrac{22}{3}\ \Omega$
So the answer is (b).
