We can Electric charge definition can be stated as the physical properties of matter which allows it to experience a special kind of force when kept under the influence of electromagnetic field. Positive and negative are the two types of electric charges. An object with a net charge equals to zero is referred to as neutral. Like charges repel and unlike attract.
Electric Charge Formula
The electric charge is measured using coulomb. 1 coulomb is the quantity of charge transferred in one second. Given by:

Where,
 E is the electric charge
 I is the electric current
 t is the time.

The study of electricity is divided into 3 different branches which are:
 Electrostatics: It is the study of the force that acts between point charges.
 Electromagnetism: It is the study of the forces that act on the charges that are in motion.
 Electric Current: It is the study of the form of energy that is associated with the flow of charge.
Types of electric charge
Two kinds of electric charges are there
 positive(+) charge
 negative() charge
 Neutral do not refer to the third type of charge, but it is a region between the positive and negative charges.
Suppose if there are identical positive and negative charges and their sum will be zero. This means they are electrically neutral.
Some of the Methods of Charging
 Induction
 Conduction
 Triboelectricity
The like charges usually repel each other and unlike charges attract each other. The SI unit for the electric charge is Coulomb and is equal to around 6.242×10^{18} e. The value of charge of an electron is −1.602×10^{19} C. Coulomb is described as the quantity of the charge passing through a crosssection of electrical conductor which carries one ampere per second.
The symbol used to denote a quantity of electricity is Q and it is directly calculated with an electrometer. When charged particles were produced by rubbing suitable materials, then we were known about the existence of charges. These facts can be demonstrated by simple examples. Take a comb and rub it on your head, place the comb near to the pieces of paper placed on the table. You will see the comb starts to attract the paper pieces.
According to the Franklin convention, the electric charge present on the comb is a positive charge and the charge present on the paper pieces is a negative electric charge. The comb which attracts the paper pieces contains positive charge and any object which repels the comb is negatively charged this is well explained through static electricity
