19.2: Electric Current
The electrical driving force across the terminals of a cell is known as the terminal voltage (difference) and is measured in volts. When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf.
What is Battery Voltage?
A volt is a potential difference across a conductor when a current of one ampere (Amp) dissipates one watt of power. Voltage is then defined as the pressure that pushes electrons (current) between two points to enable them to power something. Battery voltage refers to the difference in charge due to the difference in the number of electrons between the …

This increases the pressure (voltage) at the end of the narrower hose, pushing more water through the tank. This is analogous to an increase in voltage that causes an increase in current. Now we''re starting to see the relationship between voltage and current. But there is a third factor to be considered here: the width of the hose.
