Current electricity is used for a variety of things such as charging your cellphone, operating your computer, powering your lights, dryer, hair dryer, TV, washing machine, air conditioners, street lights and much more.

An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.

It is measured as the net rate of flow of electric charge through a surface or into a control volume.

Electricity travels at near the speed of light which is 670,616,629 miles per hour,1 or 300 million meters per second.

The speed of electrons is 1 cm/sec which is about as fast as an ant scurries on the ground.

With this simple analysis, we see that the speed of an electron in a wire is incredibly slow compared to the speed of light in air.

The word electricity refers generally to the movement of electrons through a conductor in the presence of a potential difference or an electric field.

The speed of this flow has multiple meanings.

Electrons don't move in a wire like water flows through a pipe although the electrons move across the wire along with atoms.

Any conductor (thing that electricity can go through) is made of atoms.

Each atom has electrons in it.

If you put new electrons in a conductor, they will join atoms, and each atom will deliver an electron to the next atom.

Electricity does have mass.

The invariant mass of an electron is approximately 9.109×10−31 kilograms, or 5.489×10−4 atomic mass units.

A moving magnet becomes more massive due to its increase of energy, and this additional inertia causes its electric field to increase in strength as well. Hence E = mc^2.

Electricity actually flows in wire at about the same speed of light.

The speed at which electricity flows in a wire is 670,616,629 miles per hour,1 or 300 million meters per second.

A concept called Faraday's Law recognized that when you have spinning magnets near a coil of wire, you make a voltage.

You can use that voltage to push electrons through wires and those moving electrons go to where they're supposed to be and can do work.

That's essentially how the electric grid works.

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.

Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.

Electric charge is a fundamental property of matter and is borne by elementary particles.

In electricity the particle involved is the electron, which carries a charge designated, by convention, as negative.

The 4 types of electricity are.

Static Electricity. Static Electricity is nothing but the contact between equal amount of protons and electrons (positively and negatively charged subatomic particles).
Current Electricity. Current Electricity is a flow of electric charge across an electrical field.
Hydro Electricity.
Solar Electricity.

Electric generators work on the principle of electromagnetic induction.

A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet.

The conductor coil along with its core is known as an armature.
