What is the difference between voltage and current in a battery?
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.
How does a battery produce electricity?
This reaction produces electrons, which flow through the circuit and create an electric current. Batteries are devices that store chemical energy and convert it into electrical energy. The chemical reactions inside the battery create an electric current, which can be used to power electronic devices.
What happens when a battery is connected to an external circuit?
When the battery is connected to an external circuit, such as a flashlight, the electrons flow from the negative electrode to the positive electrode, producing an electric current. This process is called oxidation-reduction (or redox for short). The chemical reactions inside the battery generate heat, so batteries can get hot during use.
What is the difference between electric current and electron?
Electron - Electrons are the charges in conductors that flow to give an electric current. Electric current - Electric current is the flow of electric charge in a circuit. Many pupils imagine electric current to emerge from a battery or a power supply and to move round a circuit in a sequential way. This leads to a consumption model of electricity.
What is the difference between a charge and a current?
Charge - Things can have an electrical charge that is positive or negative. If there is no charge, they are neutral. Electron - Electrons are the charges in conductors that flow to give an electric current. Electric current - Electric current is the flow of electric charge in a circuit.
