Answer:
Current in the battery will be 11.7 A
Explanation:
We have given that the there is parallel circuit with three different branches.
Current in each branch is 
, 
,
We have to find the current I in the battery
It is known that in parallel circuit current is sum of current in each branches
So current in the battery will be equal to
Therefore current in the battery will be 11.7 A
