Negative and Positive Polarities of Battery

We see the influence of electricity in a, static charge, battery, radio, lighting, television, and many other applications. What do they all have same that is electrical in nature?

The answer is fundamental particles of opposite polarity.

All of the materials, including liquids, solids and gases, have two fundamental particles of electric charge: the protons and electrons.

The proton is a fundamental particle with positive polarity. An electron is the smallest amount of electrical charge with characteristics called as the negative polarity. 

To use the electrical forces connected with the positive and negative charges in all of the matter, some work ought to be done to separate the protons and electrons.

Changing the balancing forces generates evidence of electricity.

A battery for example, might do electrical work because of its chemical energy separates electric charges to generate an excess of negative charge at its negative terminal and an excess of protons on its positive terminal. 

Along separate and opposite charges at the two terminals, electric energy might be supplied to a circuit linked to the battery. In below fig indicate a battery having the positive (+) and negative (-) terminals marked to emphasize the two opposite polarities.
