The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.
All these words basically describe the strength of a battery, but they’re all specifically different. Voltage = force at which the reaction driving the battery pushes electrons through the cell. This is also known as electrical potential, and depends on the difference in potential between the reactions that occur at each of the electrodes.
The current produced by a battery can be either AC or DC depending on the power source. In the case of a battery discharging, the current is DC. A direct current flows in one direction, maintaining a constant polarity. This is different from alternating current, which constantly changes direction.
As the chemistry shifts with discharge (or charge) the no load voltage changes slightly and the internal resistance changes as well. A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a battery is not an ideal voltage source.
Currently, most of the technology we use operates on either AC (alternating current) or DC (direct current) power. AC current is what we typically find in the power supply to our homes, while DC current is what batteries produce. Traditionally, batteries have been used as a source of DC power, making them suitable for a wide range of applications.
The higher the current, the more work it can do at the same voltage. Power = voltage x current. The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for.
