Which type of energy is converted into electrical energy by a battery?

Option 3 : Chemical

The correct answer is option 3 i.e Chemical,

Chemical energy is converted into electrical energy by a battery.

• A battery is a device that stores chemical energy and converts it to electrical energy.
• The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
• The flow of electrons provides an electric current that can be used to do work.
• To balance the flow of electrons, charged ions also flow through an electrolyte solution that is in contact with both electrodes.
• A battery can be made up of one or several electrochemical cells.
• The invention of the battery as we know it is credited to the Italian scientist Alessandro Volta.
