PhysicsSingle correct+4 / -1Question 37 of 90

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

Parallel combination of A and C connected in series with B.

Parallel combination of A and B connected in series with C.

Series combination of A and C connected in parallel with B.

Series combination of B and C connected in parallel with A.

Answer and worked solution

Official answer: B

Try (B). $A\parallel B=\dfrac{2\times4}{6}=\dfrac43\ \Omega$ ; in series with C: $6+\dfrac43=\dfrac{22}3\ \Omega$ .

(The others give $4+\frac32$ , $\frac{8\times4}{12}$ and $\frac{10\times2}{12}$ Ω.)

(B)
