In order ot determine the e.m.f. of a storage battery is was connected in series with a stantard cell (both are adding) in a certain circuit and a current `I_(1)` was obtained. When polarity of the stantdard cell is reversed, a current `I_(2)` was obtained in the same direction as that of `I_(1)`. What is the em.f. `epsilon_(1)` of the storage battery? The e.m.f. of the stantard cell is `epsilon_(2)`.
