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.
The voltage of a battery is also known as the emf, the electromotive force. This emf can be thought of as the pressure that causes charges to flow through a circuit the battery is part of. This flow of charge is very similar to the flow of other things, such as heat or water. A flow of charge is known as a current.
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.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
However, current more than likely won't (depending upon the age/use of the battery). The reason why is because the voltage potential difference - the "excess holes on the positive end" and the "excess electrons on the negative end" - is relative to a given battery.
So, as a general rule of thumb, batteries have a fixed voltage but: big or new batteries tend to have a low internal resistance, so they can deliver a high current small or old batteries tend to have a high internal resistance, so they can’t deliver much current This entry was posted in -- By the Physicist, Engineering, Physics.
