The stored energy of a battery is typically measured in watt-hours (Wh) or joules (J). It represents the amount of energy that can be released by the battery when it is discharged. The stored energy is determined by the battery's capacity and voltage.
The energy stored in a car battery, or other cells or batteries, is chemical energy.
A battery-powered radio operates on electrical energy stored in a chemical form within the battery. When the battery is connected to the radio, a chemical reaction releases stored energy in the form of electrical current to power the radio's components.
A battery converts chemical energy stored in its cells into electrical energy. When a circuit is connected to the battery, chemical reactions occur within the battery that release electrons, generating an electric current.
Kinetic energy being converted to chemical potential energy
A torch typically uses chemical energy stored in a battery or fuel cell to produce electrical energy for the light source, which then converts it to light energy.
In most cases, chemical energy stored in the battery produces the electric current. Rechargeable batteries are capable of taking electric currents and using them to reverse the chemical reactions, thus gaining more chemical energy that can be used readily.
The energy stored in oil and coal is stored as chemical energy. This energy is released when the substances are burned or oxidized.
POTENTIAL ENERGY
Batteries produce electrical energy through a chemical reaction that converts stored chemical energy into electrical energy. This electrical energy can then be used to power various devices.
Potential energy is stored in natural gas.
