In the circuit shown the effective resistance between B and C is

A)  \[3\,\Omega \]                          

B)  \[4\,\Omega \]

C)  \[4/3\,\Omega \]                        

D)  \[3/4\,\Omega \]

Correct Answer: C

Solution :

 \[{{R}_{eq}}=\frac{{{R}_{1}}{{R}_{2}}}{{{R}_{1}}+{{R}_{2}}}\](Prallel) \[=\frac{4\times 2}{4+2}=\frac{8}{6}=\frac{4}{3}\Omega \]
