WebFeb 24, 2012 · Hence it can be concluded like that, a battery is a combination of several cells where a cell is a unit of a battery. For example, Nickel-cadmium battery cells normally develop about 1.2 V per cell while lead acid battery develop about 2 V per cell. So a 12 volt battery will have total 6 number of cells connected in series. EMF of Battery WebBoth emf (electromotive force) and pd (potential difference) are measured in V (Volts) Electromotive force (emf) formula can also be written as, e = IR + Ir or, e = V + Ir Where, e is the electromotive force (Volts), I = current (A), R = Load resistance, r is the internal resistance of cell measured in ohms. highest road in switzerland https://britfix.net
