Q. Thirteen resistance each of resistance $R\ ohm$ are connected in the circuit as shown in the figure below. The effective resistance between $A$ and $B$ is
A) $2R\ \Omega$
B) $\frac{4R}{3}\ \Omega$
C) $\frac{2\ R}{3}\ \Omega$
D) $R\ \Omega$
Explanation
(c) Hence $R_{eq} = \frac{2R}{3}$ [Since it’s a balanced Wheatstone bridge]
