Where does Electricity really come from?
Where does the water come from?How you pump water through a pipe? You use a pump which pushes the water molecules (gives them energy or applies a force) and they flow through the pipe.
Electricity works in a similar manner. However, the thing which flows are electrons inside conductors. Electrons flow due a pump action like in a water system. The pump can be a voltage difference between two points or a changing magnetic field which causes the electrons to move.
The basic idea is that electric energy is caused by the movement of electrons inside conductors (wires) by some kind of force. People invent some machines/devices (batteries, generators, etc) which are able to produce this force and create electricity.
OK! So Electricity is energy... where does it come from? what form is it converted from? Why does it only move with a magnet and a coil and not with some other material and a coil? If it is the movement that "converts" the energy Why can't you achieve the same effect using wood or plastic?You're being obtuse. Think conversion. Electricity is energy, it started as some other form of energy, such as water flowing over a cliff, or steam turning a turbine. At the end of the long chains of conversions it ends up as heat, or electromagnetic radiation.
The example of moving the magnet through a coil, for example, the source of the energy is the movement itself.
The big secret of the modern age of technology, how to convert one form of energy into another. Some of the concepts are hard, but the information is available to all who are willing to study.
Plastic, Wood, Rubber and Glass don't have enough Free Electrons to conduct electricity well. Be happy about that because they fall into the category of Insulators. When talking about wood, it's a relative thing because all wood holds moisture and minerals that will conduct, especially at very high voltages.OK!
