# The static electricity and the current (dynamic) electricity

### The electricity

The electricity is produced from the electric charges when these electric charges are stable on a body, the produced electricity is the static electricity and when the electric charges flow through a conductor (wire), the produced electricity is the dynamic electricity.

#### The static electricity

The static electricity is a type of electricity that is formed from the electric charges that remain on an object, and rubbing of the objects generates the static electricity.

There are some phenomena related to the static electricity as the vision of the light in the sky which is called the lightning,  standing of your hair during combing it by a plastic comb, and hearing a sound when you put off your clothes.

There are two types of electric charges which are the positive charges and the negative charges, The lightning happens when positive electric charges found in the clouds meet with the negative electric charges rising from the Earth.

##### The current ( dynamic ) electricity The dynamic electricity

The current electricity is the electric charges that flow through the connecting wires for the long distances forming the electric current, The electric current is the movable electric charges when the electric current flows through a wire in one direction, it is called a direct current.

To obtain the electric current or the dynamic electricity, we need to form an electric circuit which is composed of a battery, a lamp, the connecting wires and the electric switch (the key).
