The total current supplied to the circuit by the battery is:                  

A)  1A                              

B)  2A                   

C)  4A               

D)  6A                  

Correct Answer: C

Solution :

Here, from the circuit on right New resistance \[=\frac{3}{2}\Omega \]   (\[\because \] \[2\,\Omega \]and \[6\,\Omega \] in parallel) Then by Kirchhoff?s law             \[6=\frac{3}{2}i\] \[\Rightarrow \]               \[i=4A\]
