The protons are positively charged and are found "locked" in the nucleus with the neutrons
The electrons are negatively charged and are moving around the electron clouds, and are not "locked" into position
Electricity is the free movement of electrons
Current = the rate of movement of electrons can be measured over a certain amount of time - the speed of which the electricity is moving
Sometimes, the flow of electrons is slowed down by any number of factors include:
Materials - what the electrons are moving through
Temperature - how warm or cold the materials are
Length - how far the electrons need to move
Cross section - how wide the area is the electrons are trying to move through
Battery - a device that converts chemical potential energy (CPE) to electrical potential energy (EPE)
Electrical potential energy is changed to thermal energy, light, mechanical energy as the electricity moves through the different materials.
A circuit is a complete path for the movement of a charge
