Two batteris of emf `epsilon_(1)` and `epsilon_(2)` wit respective internal resistance `r_(1)` and `r_(2)` are connected in parallel. Now

A

The effective emf of this parallel combination is `((epsi_(1)r_(1)+epsi_(2)r_(2)))/((r_(1)+r_(2)))`

B

The effective internal resistance of this combination is `(2r_(1)r_(2))/((r_(1)+r_(2)))`

C

the effective emf of this parallel combination is `((epsi_(1)r_(2)+epsi_(2)r_(1)))/((r_(1)+r_(2)))`

D

The effective internal resistance of this combination is `(r_(1)r_(2))/((r_(1)+r_(2)))`
