When current flows from a battery, does voltage decrease?
I understand voltage to be a potential for electrons to be pushed through a circuit. However, in a battery, you have an electron build-up that creates the voltage. Once current begins to flow, electrons are now moving through the circuit. Does this mean that the voltage actually begins to decrease as a direct result of current flow?
Does current flow inside a battery?
$begingroup$ Without continuous current, the formed charge disbalance would very quickly form potential countergradients, ceasing any external current.

Physics Tutorial: Electric Current
If the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current - a flow of charge.
