Electrons along with protons and neutrons are what make up atoms. The basic charge on an electron is measured in terms of coulombs. One coulomb of charge is equal to the amount of charge carried by one ampere in one second.

Electrical conductors are materials with elements that have a weak attraction between atoms and their electrons. In conductive elements, electrons tend to move from atom to atom.
-
-
Chemical elements on the periodic table are made up of different types of atoms. The attraction between atoms and their outer electrons is stronger in some elements than in others.
-
-
Electric current is created from the movement of electrons. Current flows in a closed loop and is constant everywhere in that loop.
-
-
Atoms are the building blocks of all elements and matter. Electrons carry negative charges and are attracted to the positively charged protons within the nucleus of the atom.
-
-
Electrical insulators are materials made up of elements that strongly attract their electrons and in which the electrons never leave the atom. Examples of materials that are electrical insulators are dried wood, glass, and various rubber materials.

Voltage is the force that drives current. It can also be referred to as electric pressure. Voltage is measured as the difference in electric potential energy between two points.
-
Amperes (Amps) measure the strength of electric current. Amperes are a measure of the number of electrons in an electric current. One ampere per second is equivalent to one coulomb traveling through a circuit in one second. This is roughly equivalent to the flow of 6.241509×10^18 electrons per second.

An electrical circuit is a physical network (or model of a physical network) of interconnected electrical components including batteries, resistors, capacitors, inductors, and switches.

Power is the amount of energy consumed over time. Power is measured in Watts. The basic formulation of power is power = voltage x current.
