The work done by a battery is `W=epsilon Deltaq`, where `Deltaq=` charge transferred by battery `epsilon=` emf of the battery. What are dimensions of emf of battery?

The emf of the battery shown in figure is

The emf of the battery shown in figure is

The emf of the battery shown in figure is

The EMF of Ni-Cad battery is dependent of :

The energy transfered to the battery of an invertor from the electric line is given by U=E.q where q = charge transfered. If A is the ammeter reading during transfer for a small time Deltat , then the dimensions of e.m.f. E of the battery are :

The plates of a parallel plate capacitor are charged with a battery so that the plates of the capacitor have acquired the P.D. equal to e.m.f of the battery. The ratio of the work done by the battery and the energy stored in capacitor is

How is emf generated in: A battery.
