A battery diagram is a graphical representation of a basic battery circuit. It helps to illustrate how a battery is connected in a circuit and how the current flows within the circuit. By understanding the basic concept of a battery diagram, one can have a clear visual understanding of how a battery functions in an electrical circuit.
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?

An electric current, which is a flow of charge, occurs when there is a potential difference. For a current to flow also requires a complete circuit, which means the flowing charge has to be able to get back to where it starts.
