I have a physics book that describes a battery in a circuit as like a pump that provided energy to the charge (e.g. a 1.5 volt battery gives 1.5 joules of energy to each coulomb of charge).
Am I right in assuming that the energy in a circuit is directly derived from the chemical/electrical energy generated by the battery?, Or does the battery provide the difference in emf that drives the movement of the charge?
maybe the "pump" analogy is giving me a wrong idea?
Just need to clear this up in my head 'cos I can't move on until I do
