What are electric charges?
Electric charges are the physical property of matter, which causes it to experience force when placed in an electromagnetic field. There are generally two types of electric charges – positive and negative charges, and which we also know as protons and electrons. We are also called like charges and unlike charges, like charges i.e. positive charges and unlike charges i.e. negative charges.
An object without a net charge is referred to as neutral. Early knowledge of the interaction of charged materials is now called classical electrodynamics and is still accurate for problems that do not need to consider quantum effects.
Definition of electric charges
When a body exhibits two properties of electric charges like and unlike, then they attract and repel each other, it is called electric charge. Its unit is coulomb and is represented by “C”. And charges are denoted by Q or q.
We can also call electric charges like and unlike charges i.e. attraction and repulsion between positive and negative charges. (The attraction and repulsion of like and unlike charges are called electric charge.)
The SI unit of electric charge is named after the French physicist Charles Augustin de Coulomb. In electrical engineering, it is common to use ampere-hours (Ah). In physics and chemistry, it is common to use the primary charge (e as a unit). Chemistry also uses Faraday as a charge on one mole of electrons. The symbol Q often denotes charge, also read Coulomb’s biography.
