The cells of emf's `E_(1) and E_(2)` be connector in parallel in a circuit. Let `r_(1) and r_(2)` be the internal resistance of the cells. Then the current through the circuit is

A

`(E_(1)+E_(2))/((r_(1)+r_(2)))`

B

`(E_(1)-E_(2))/((r_(1)+r_(2)))`

C

`(E_(1)+E_(2))/((r_(1)-r_(2)))`

D

`(2(E_(1)+E_(2)))/((r_(1)+r_(2)))`
