I see much confusion concerning what electricity is, what it does and how it works so I thought a primer was in order.

To understand electricity only a few key concepts are required relating to Force and Flow. We could start with a simple circuit which contains a battery, two wires and a light bulb.

The battery is just an electron pump which uses an internal chemical reaction to push electrons towards the (-) terminal and pull electrons from the (+) terminal. The battery does not create electrons nor does it destroy them it simply produces a force or electrical pressure(-) and an equal and opposite electrical suction(+) which causes the electrons to move like a pump causes water to move. As well, like fields repel and unlike fields attract therefore all the electrons at the (-) terminal with like fields want to move away from one another while also being attracted to the (+) terminal with opposite fields. This is the source of the electrical force which causes the free electrons to move through the circuit from the (-) terminal through the wires and bulb then back to the (+) terminal. The battery acts exactly like a water pump having a pressure discharge (-) and a suction inlet (+) only the medium flowing is free electrons.

The electron pump analogy also simplifies another concept which seems to confuse many people. That is the difference between "potential" and a "potential difference". Think of it this way, if my electron pump pressure at the (-) terminal is 2 psi of electrical pressure and my pump suction at the (+) terminal is minus 2 psi then the difference between the (-) and (+) terminal is 4 psi. Likewise if a 12v battery has a pressure or potential of 6 at the (-) terminal and a suction or potential of negative 6 at the (+) terminal then the total difference or difference in potential (potential difference) is 12 volts. Count from negative 6 through zero up to 6 and the total difference is 12.

I understand this is very confusing for many because I am using "electron flow notation" based on the reality of what actually happens in reality within every circuit. We have known for decades that no positive (+) charges "flow" in a circuit because the only positive charges present are the Protons in the atoms and they cannot move. The circuit is made of atoms with Protons (+) and Electrons (-) however the Protons cannot move in the conductors otherwise the metal of the conductor itself would flow like a fluid which it does not. Therefore in reality the only thing in the conductors of the circuit left to move or conduct are the free electrons.

You see the reason nothing seems to make sense is because most are still using the completely outdated and completely false notion taught in textbooks that (+) charges "flow" in a circuit or conventional notation. Electron flow notation describes most everything in the circuit as it happens in reality. As well no credible Scientist or Engineer uses conventional notation because it simply does not reflect the reality of what does happen.
