Electricity what is it? Electricity is also known as electrical energy which is the flow of moving electrons. Electrons are from atoms which have three different components with different charges. There are protons with a positive charge, neutrons with a neutral charge, and electrons with a negative charge. But the negatively charged electrons are useless if they don’t have a circuit to travel on. A circuit is a system that is made of three different components and they are: an energy source, a load or resistor, and a conducting wire, but there is the option to use a switch. Each component has a different role in a circuit. An energy source is the source of the energy, the load or resistor is what uses the electricity, the conducting wire is what connects the circuit, and if you use the option of a switch you can stop the flow of electrons from going through the circuit. If one of the main components is missing then the circuit will not work., but if the switch is not in the circuit the flow will continue. There are two different types of circuits and they are parallel and series. A series circuit is a circuit with only one path for the electrons to flow, meanwhile a parallel circuit has several paths for the electrons to flow. In a series circuit if even one part of it stops working then the whole circuit stops working. For example if you have a simple circuit with a battery, conducting wires, and two light bulbs and one of the bulbs blew out then the other stops working as well. A parallel circuit on the other hand is designed where there are many different paths for the electrons to follow, so if a bulb goes out or if a wire gets damaged then the circuit will still continue to work. But parallel circuits are more complex and expensive to create. There is no point to a circuit if you don’t have anything to flow through it, so thats where moving electrons known as an electric current is useful. An electric current is the electrons that flow
