The current from the battery in circuit diagram shown is                                                                       [IIT 1989]

A)                    1 A

B)                    2 A

C)                    1.5 A

D)                    3 A

Correct Answer: A

Solution :

             The given circuit can be simplified as follows       On further solving equivalent resistance \[R=15\,\Omega \] Hence current from the battery \[i=\frac{15}{15}=1A\]
