Answer 1

What are electrons and how are they involved in creating and electric current?

Answer 2

They are negatively charged particles surrounding the nucleus of an atom. Whe they are not tranfering current, they are arranged haphazardly, but when they do conduct current, they are arranged in a given order and direction and the the electric charged is passed from one electron to another. Basically they are static, that is why there is tranfer of charge from one electron to another.

Answer 3

Electrons in conductors are the main contributors to "current", in fact current is the rate movement of electrons in a conductor. The electrons within a conductor or loosely bound and when a potential difference or voltage is applied at the opposite ends of the conductor, the electrons flow from the point of lower potential to higher potential. The electron charge is measured in coulombs, the definition of current is the number of coulombs per second that pass a given point.

Answer 4

The electron is a subatomic particle carrying a negative electric charge. It has no known components or substructure, and therefore is believed to be an elementary particle.The structure of an atom has a dense nucleus of positive charge surrounded by lower-mass electrons.Electrons have an electric charge of −1.602×10^−19 coulomb, which is used as a standard unit of charge for subatomic particles.

Electric current means, depending on the context, a flow of electric charge (a phenomenon) or the rate of flow of electric charge (a quantity). This flowing electric charge is typically carried by moving electrons, in a conductor such as wire; in an electrolyte, it is instead carried by ions, and, in a plasma, by both.
The SI unit for measuring the rate of flow of electric charge is the ampere, which is charge flowing through some surface at the rate of one coulomb per second.
