HOPE IT HELPS U✌

Answer 2

The device is a battery

• A battery is made up of a collection of cells that work together to create a potential difference. A single unit that makes up a battery is called a cell.
• They contribute to the maintenance of a potential difference which then creates the current flow.
• Almost all electric equipment, such as torches, cell phones, and electric cars, use them as a portable source of power. These are the several sets of plates that each serve as a cell.
• These batteries differ from normal cells in that they have been modified to produce more electricity for power needing electronics.
