Hello everybody
can anybody explain to me why there is potential difference in the battery (and when we say the potential difference of the battery is Va-Vb =12 v can both electric potentials be positive for example Va=20v and Vb =8v ) . From the last , can somebody illustrate to me in a deep way how the battery works and how it produce emf..?
and thanks a lot .
