What is electricity?

This is an conductor; it lets charges flow easily through it, unlike a insulator.

Lightening is an example of static discharge. Static discharge is the loss of static electricity as electic charges transfer from one object to another.

An electric circuit is a complete, unbroken path through which electric charges can flow. For example, you go for a walk. You're walking, then all of a sudden the road you were walking on is blocked due to repairs. Your path has been broken. This is the same with a circuit. A circuit flows continously, but once there is something blocking its path, it stops.

What is electricity?

These rubber bands are insulators, and do not let charges flow easily through them.

Voltage: the difference in electric potential energy per change between two points in a circuit. This energy difference causes the charges to flow!

There are four way that an object can become charged by: by friction, conduction, induction, and polarization.

The first, charging by friction, is the transfer of electrons from one uncharged object to another by rubbing the objects together.

Charging by conduction is when someone makes direct contact with something, making electrons transfer. Electrons always transfer from the object they start out from, which has more negative charges, to the place their conductor touches, which is more positive.

Electrons can also react and transfer to another object without being in contact with it directly. If there is a negatively charged object near a metal, the side of the metal nearest to the object will turn positive, and vice versa when the metal is originally positive. This is charging by induction

An atom is made up of electrons and protons, and has the same amount of each. This makes the atom neutral.If as atom loses electrons, it then has more protons than electrons, making it a positive charge, and vice versa. So, the buildup of charges is static electricity. They indeed build up, but never flow continuously.

Potential energy affects the flow of both water and electric currents, even though water currents use gravitational potential energy and electric currents use electric potential energy.

Electrons, as well, can react to eletric fields, which results in the elctrons having charged ends, and makes them attract to other charged objects. This is called charging by polirazation.

When eletric charges need to flow through a material, it creates a eletric current. An eletric current is the continous flow of eletric charges.
