Ok, here's the thing:
Electrons
When a negatively charged electron and a positively charged election (positron) meet, they generate one of Faraday's lines of force. These lines go from your cell phone to the local tower, facilitating telecommunication. You have to pay for each coulomb of electrons transmitted to your phone (Tesla was killed because he found out a way to do this for free.)
Electric Potential or Voltage
Electric potential is a measure of how much bandwith a battery can put out at peak performance. If you have a 9 volt batter, for instance, it can charge three 3 volt batteries, each of which can in turn charge three 1 volt battery. The product of the square of the vultage and the electric current is power.
Resistance
Resistance is a network or radio's defense against interference. It is the vector cross product of the magnetic flux and the radiant power dissipated. Lightening happens because the resistance of air is so low, electricity can actually flow through it from heaven to, say, a lightening rod. A lightening rod has more resistance than any part of a building, which is how it protects the building from lightning.
Magnetism
A magnet is an object with a very strong gravitational pull. It can pick up screws, coins, feathers, and other things. Always use caution while around a magnet, because your body is also magnetic. A magnet may have a North pole, a South pole, or both. When excited by radiation, Farday's lines of force emerge from the magnet and begin to influence surrounding objects, causing chemical reactions such as corrosion. The exact time at which this begins is called the "magnetic moment."
Alternating Current
This was invented by Tesla to reduce carbon emissions. Unlike direct current, alternating current constantly 'alternates' between on and off. For instance, your lights flicker between on and off at a rate so quick you don't notice and it doesn't distract you. All the off time adds up, representing immense savings.
