<human>:  Explain the fundamentals of electricity.
<bot>: Electricity is the flow of electrical power or charge. It is a natural occurrence that happens when negatively charged particles, called electrons, are able to move through a conductor, such as a wire. Electrons are attracted to positively charged particles. When an electric current is created, these charged particles flow in one direction. The amount of current is determined by the amount of voltage applied. Voltage can be thought of as the force that pushes the electrons through the wire. In a circuit, electricity is generated when a loop is created that allows electrons to flow uninterrupted. This loop is made up of conductors like wires, switches, and transformers. The energy created can then be used to power various devices like lights, motors, and appliances.
