About Electricity ppt

Md Nur Shahadot presented on electricity and related concepts. Electricity is the flow of charge and is a basic form of energy associated with electric charge. Charge is a fundamental property of elementary particles like electrons and protons that creates forces between them. Coulomb's law states that the electrostatic force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The electric field is the region around a charge where it can exert attractive or repulsive forces on other charges. Electric field lines provide a visual representation of the direction and strength of the electric field.
