Two batteries of emf `epsilon_(1)` and `epsilon_(2) (epsilon_(2)gtepsilon_(1)` and internal resistances `r_(1)` and `r_(2)` respectively are connected in parallel as shown in Fig. 2 (EP).1.
A. Two equivalent emf `epsilon_(eq)` of the cells is between `epsilon_(1)` and `epsilon_(2),i.e.,epsilon_(1)ltepsilon_(eq)lt epsilon_(2)`
B. The equivalent emf `epsilon_(eq)` is smaller then `epsilon_(1)`
C. The `epsilon_(eq)` is given by `epsilon_(eq)=epsilon_(1)+epsilon_(2)` always
D. `epsilon_(eq)` is independent of internal resistances `r_(1)` and `r_(2)`
