Electricity is the form of energy generated by the flow of electrons
Current describes the flow of electricity
Insulator And Conductor
A insulator is a substance that restricts the flow of heat or electricity
A conductor is a material that allows the flow of heat and electricity
Electrical Circuit
An electrical circuit is a path that allows electric current to flow
A electric circuit is a point between two opposite electrical charges
Electrons move through the electrical circuit from negative to positive or the way around
This electrical circuit is connection to a battery

The battery pushes out electrons from one end to the other positive side of the battery
The energy transfer will be equal as one electron is released when one electron is taken from the battery
The key to make a electric circuit is to make a continuous electric flow
When there isn't any resistance to a circuit, it can potentially heat up and burst
