Question
Thirteen resistances each of resistance $\mathrm{R} \Omega$ are connected in the circuit as shown in the figure the effective resistance between $\mathrm{A}$ and $\mathrm{B}$ is...(A) $(2 \mathrm{R}) \Omega$(B) $(4 \mathrm{R} / 3) \Omega$(C) $(2 \mathrm{R} / 3) \Omega$(D) $\mathrm{R}$
Step 1
Two resistances in series simply add up. So, the two resistances on the top left, the two on the top right, and the two on the bottom right each add up to $2R$. Show more…
