The Fuel Cell
In a mobile device, the battery (chemical energy) converts into electrical energy to power the device. When the phone is being used, the electrical energy powers the various components of the phone, such as the screen, processor, and antenna.
A battery is a device that turns chemical energy into electrical energy by using chemical reactions to generate a flow of electrons.
The motor changes electrical energy into mechanical (torque) energy.
A device that turns chemical energy into electrical energy is called a battery. Batteries store and release electrical energy through chemical reactions happening inside them.
A battery is a device in which chemical energy is transformed into electrical energy.
An electrical generator
An example of a change from chemical energy to electrical energy is when a battery powers a device such as a smartphone. The chemical reactions inside the battery generate electrical energy that is then used to power the device.
Cell
A battery is a device that converts electrical energy into chemical energy for storage and subsequent use in powering electronic devices.
A battery is a device that stores and produces electrical energy by converting chemical energy into electrical energy through electrochemical reactions.
