Time Varying Voltages
... We have talked about the electromotive force (e.m.f.) created by chemical means in batteries. Batteries produce an e.m.f. that does not change as time passes – at least it doesn’t change up until such time as the battery wears out. There are other sources of e.m.f. that do change their amplitude as ...
