The equivalent resistance between A and B will be  

A) \[\frac{8}{3}\Omega \]              

B) \[\frac{25}{4}\Omega \]

C) \[16\,\Omega \]                          

D) \[\frac{3}{20}\Omega \]

Correct Answer: B

Solution :

[b] Equivalent circuit can be written as, \[\equiv \,\,R=\left( 2+\frac{9}{4}+2 \right)\Omega \] \[=\frac{25}{4}\Omega \]
