Under what condition, the current passing through the resistance R can be increased by short - circuiting the battery of emf `E_2` The internal resistances of the two batteries are `r_1 and r_2,` respectively.

`E_(2)r_(1) gt E_(1)(R + r_(2))`

`E_(1)r_(2) gt E_(2)(R + r_(1))`

`E_(2)r_(2) gt E_(1)(R + r_(2))`

`E_(1)r_(1) gt E_(2)(R + r_(1))`
