Electricity is the flow of electrons. It can be captured in certain liquids and solids.
The Circuit is currently as of July 6, 2019, the only way to harnesses electricity and put it to work. Most circuits have These components.
The power source of a circuit supplies electrons and when the electrons are finished it takes the back. Without a Power Source, it would not be powered.
Resistors diffuse some of the electric and may have a proper function like a light bulb or a fan. Anything that consumes electricity and gives less back is a resistor. Always have a resistor in your circuits. It there is no resistance the current is 100%. Also, the resistor needs to be big enough.
These components allow you to do a variety of things.
Capacitors store DC energy and releases it later. Capacitors only store DC and let AC pass though with a little resistance.
These direct current different ways.
Sensors detect and/or measure input.
