Eight resistances each of resistance \[5\Omega \] are connected in the circuit as shown in figure. The equivalent resistance between A and B is -

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

B) \[\frac{16}{3}\Omega \]

C) \[\frac{15}{7}\Omega \] 

D) \[\frac{19}{2}\Omega \]

Correct Answer: A

Solution :

The given circuit can be redrawn as \[\therefore \,\,\,\,{{R}_{AB}}=\frac{8}{3}\,\Omega \]
