definition of electric charge

At the behest of the Physical the electric charge turns out to be a Intrinsic property that some subatomic particles present which will be manifested through attractions and repulsions that will determine the electromagnetic interactions between them, being the same positive charges and negative charges.

Electrically charged matter will be influenced by electromagnetic fields at the same time that it generates them.

The interaction between charge and electric field will give rise to one of the four fundamental interactions, which is the electromagnetic interaction.

Historically, electrons, quarks and protons they were assigned different charges, for example, electrons present negative charge -1, also known as -e; on the other hand, the protons have a charge positive +1 or also + e, meanwhile, to the quarks they were assigned a fractional charge.

According to what the International System of Units the electric charge is called coulomb (c) and defines it as that amount of charge that passes through the cross section of a certain electrical conductor during the period of one second and when the electrical current is one ampere.

The nature of the electrical charge is discrete.

Since ancient Greece, the property of attraction of light bodies that some materials show began to be studied, while it was only in the middle of the 19th century when all the observations obtained from Ancient Greece would be formally systematized.
