Electrical Charge
Current
Current is the rate of flow of Charge
I = Δq/Δt
Current
Voltage
Voltage (Potential Difference) is the change in energy (work done) to each coulomb of charge between two points on a circuit, or two points across an electric field

Internal Resistance of a Battery
Batteries can be thought of as having an ideal voltage supply E.M.F. (Electromotive Force) in series with an internal resistance
V = 𝛆 - Ir
