Find the equivalent resistance. across the terminals of source of e.m.f. 24 V for the circuit shown in figure

A) \[15\Omega \]    

B) \[10\Omega \]

C) \[5\Omega \]     

D) \[4\Omega \]

Correct Answer: C

Solution :

[c] Given circuit can be reduced to a simple circuit as shown in the following figures So equivalent resistance\[=\frac{10\times 10}{10+10}\Omega =5\Omega \]
