26-1 EMF and Terminal Voltage
Electric circuit needs battery or generator to produce current – these are called sources of electromotive force (emf).
emf is not a force but a voltage
Battery is a nearly constant voltage source, but does have a small internal resistance, which reduces the actual voltage from the ideal emf.
