All Videos In The Series, "How to Build Electronic Circuits"
Electricity is a complicated phenomenon. Within attempting to control it there are networks, which are connections of two or more electrical elements (ie.- resistors, capacitors, switches) and circuits, which is a network that has what is called a closed loop. This closed loop allows for a return path for the electrical current. In order to design an electrical current the output and the input of the voltage running through it must be equal. The complex number theory is used to establish this relationship.
Does this sound difficult? It probably does to most people. Don't feel overwhelmed. Iin this step by step free video series it will not only be better explained but Ross Safronoff, our expert, will show you how simple it really is and how to put it to work for you. Electricity is very powerful when harnessed correctly. He will walk you through every piece of equipment and detail of how electricity works and how we use it to our advantage as well as show you how to put it to use on a garage door.
"Hello! This is Ross on behalf of the expertvillage.com. We are all outside because all basic electronics start with a great water analogy. This garden hose represents a piece of copper wire. Copper wire is an excellent conductor for electrons. That's what we're talking about electron flow here, I have a model of an atom. Now you are probably familiar with atoms. This one is into scale as a matter of fact atoms are still small and you cannot see even them. Also this being a copper atom, is not configured correctly because this being in the middle, the protons, the neutrons, the outside shells or orbits if you will there are four of them 1, 2, 3 and 4. There are 29 electrons total. So it is not quite perfect. Use your imagination if you will. What happens in the copper electron because the outside only has one electron orbiting, it is very easily knocked away, later Pluto. So anyhow as it moves off because of the voltage, the pressure, the push, the electromotive force, it goes down the wire. The greater the push, the more electrons are freed off and they move. Now the garden hose, same idea, there is no water flowing out of it right now, no not yet. There is no water flowing out of it yet because there is no pressure applied to it. A spicate, which will be like a switch, you will like switch it to turn on and off, that spicate is off right now. No water flows. Turn the spicate on and there is pressure already behind that hose ready to flow and that flows and it goes down. So with the spicate off, there is no flow with a turned on though... with electronics the pressure is created with voltage."
