electricity
Electricity is a form of energy caused by the movement of tiny particles called electrons.
Electrons have a negative charge and move from one atom to another, creating an electric current.
Electricity can be found naturally, such as in lightning, or it can be generated by people.
When electrons move through a conductor like a metal wire, electricity flows and powers devices.
Static electricity happens when electrons build up in one place and cause a sudden flow, like a spark.
Electricity needs a closed path called a circuit to flow and power things like lights and machines.
The flow of electricity is measured in units called amperes or amps.
Voltage is the pressure that pushes electricity through a circuit, like water pressure in a pipe.
Materials that allow electricity to flow easily are called conductors, while those that block it are insulators.
We rely on electricity for almost everything in daily life, from lights and computers to refrigerators and phones.
