Mention the use of battery in an electric circuit Class 10

What is a battery for Class 7?

Battery – A battery is a combination of two or more cells combined in series to produce higher electricity . It is used in applications where more electricity is needed like torch, toys, UPS, Car etc.

Battery. A cell is a single unit device which converts chemical energy into electric energy . A battery usually consists of group of cells. Depending on the types of electrolytes used, a cell is either reserve, wet or dry types. Cell also includes molten salt type.

Answer: When two or more cells are joined together , it is called a battery. Question 3.

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.

What is a battery?

A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction . This type of reaction involves the transfer of electrons from one material to another via an electric circuit.
