Basic Electronics

Hello, here you can find knowledge that will be needed in order to start working with electronics! The following information won't address you as engineers, scientists or technicians, but as artists and designers.

What is Electricity?

Electricity seems to be both familiar and yet abstract. Its quite hard to imagine.

Electricity is an essential ingredient of matter. Sounds poetic, doesn't it? So to picture it, lets zoom deep in and look at the smallest component of every element - the atom.

Atoms are made of even smaller particles called protons, neutrons, and electrons. The protons and neutrons are packed tightly together in the middle of the atom, and we call them the nucleus of the atom. The electrons orbit around the nucleus. Protons and electrons have electrical charges. Protons have a positive charge, and electrons have a negative charge (neutrons don't have any charge). Normally an atom has equal numbers of protons and electrons, so they cancel each other and the atom has no electrical charge. Sometimes an electron does escape from its atom and runs off to join another atom. That's a little tiny bit of electricity. Electricity is electrons that have gotten loose from their atom.

In order imagine electricity, there is an analogy that is famously used. It is that of water, since we all have seen it, and know its behavior.
