Question

explain battery and dry cell​

Answer 1

Battery:

• A battery could be a device that stores energy and converts it to electricity.
• The chemical reactions in an exceedingly battery involve the flow of electrons from one material (electrode) to a different, through Associate in Nursing external circuit.
• The flow of electrons provides an electrical current that will be wont to work.
• A battery will be outlined as an Associate in Nursing chemical science device (consisting of 1 or a lot of chemical science cells) which will be charged with an electrical current and discharged whenever needed.
• Batteries square measure typically devices that square measure created from multiple chemical science cells that square measure connected to external inputs and outputs.

Dry Cell​:

• It is usually employed in torched, transistors, radios, calculators, tape recorders, etc.
• It consists of a hollow atomic number 30 cylinder that is full of a paste of NH4​Cl and a bit ZnCl2​.
• This paste is created with the assistance of water. The atomic number 30 cylinder acts as an Associate in Nursing anode whereas the cathode could be a carbon rod (Carbon).
• Many common batteries, like those employed in an electric lamp or device, square measure voltaic dry cells.
• These batteries square measure referred to as dry cells as a result of the solution could be a paste. they're comparatively cheap, however, don't last an extended time, and don't seem to be reversible.
