||An atom is the basic component of a chemical element, but atoms themselves are composed of various combinations of smaller, or subatomic, particles, such as electrons, protons, and neutrons.
||Electronics is the study and use of devices that operate by controlling the flow of electrons or other electrically charged particles.
||Induction coils operate according to Faraday's law in order to step up the nominal battery voltage to the voltage needed to bridge the gap across the spark plug electrodes.
||A stepper motor rotates in a series of very precise steps, controlled electronically by a microprocessor.
||Tolerance in engineering is an allowance made for imperfections in a manufactured object.
|Transformer||A transformer is an electrical device that transfers energy from one electrical circuit to another by magnetic coupling without moving parts.|
