An electric charge is a physical quantity and property of matter that causes it to experience a force when placed in an electromagnetic field. Apart from having a magnitude and direction, a quantity to be termed a vector should also obey the laws of vector addition, such as triangle law of vector addition and parallelogram law of vector addition; only then the quantity is said to be a vector quantity. Electric charge is carried by subatomic particles and there are usually positive and negative electric charges present. Electrons carry the negative charge and protons carry the positive charge in the nuclei of atoms. Electric charges are of two types: Positive and Negative, commonly carried by charge carriers protons and electrons. Electric charge is the fundamental physical property of matter because of which the matter experiences a force whenever it is kept in an electromagnetic field. In electrical engineering, it is also common to use the ampere-hour (Ah), and, in chemistry, it is common to use the elementary charge (e as a unit). Then the SI unit of charge is coulomb and its symbol is C. Therefore, charge = electric current time. One coulomb is defined as the amount of electric charge per unit. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp.
