William Gilbert, an English physician, was the first to study electricity's phenomena and properties in detail. His work laid the foundation for future research in electricity and magnetism.

The unit of electric charge is the coulomb, named after Charles-Augustin de Coulomb. One coulomb represents the amount of charge transferred by a current of one ampere in one second.

In general, electricity is classified into Both static electricity and current electricity (which includes both AC and DC).

Static electricity refers to the buildup of electric charge on the surface of objects, while current electricity involves the flow of electric charge through a conductor.

One Ampere is the unit of electric current, defined as one coulomb of electric charge passing through a conductor in one second, symbolizing the flow of electric charge.

Materials that do not allow the flow of charge are called Electrical Insulators. They resist the movement of electric charge, preventing the flow of electricity.

The best electrical conductors are Mercury and Ordinary water. However, it's important to note that while ordinary water contains ions that can conduct electricity, pure water is a poor conductor.
