Question

what is battery .....................​

Answer 1

Answer:

A battery converts chemical energy into electrical energy by a chemical reaction. Usually the chemicals are kept inside the battery. It is used in a circuit to power other components. A battery produces direct current (DC) electricity (electricity that flows in one direction, and does not switch back and forth).

Explanation:

There are some other types of Secondary Batteries but the four major types are: Lead – Acid Batteries. Nickel – Cadmium Batteries. Nickel – Metal Hydride Batteries. Lithium – Ion Batteries.

Answer 2

Electric battery

• A battery is a device consisting of one or more electrochemical cells with external connections for powering electrical devices such as flashlights, mobile phones, and electric cars.

• When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.

• The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal.

• When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy.
