| Term | Definition |
|---|
| Semiconductor | is a material whose resistivity is between that of a good conductor and a good insulator. |
| Intrinsic Conduction | is the movement of charges through a pure semiconductor. |
| Extrinsic Conduction | is the movement of charges through a doped semiconductor. |
| Doping | is the addition of a small amount of atoms of another element to a pure semiconductor to increase its conductivity. |
| n-type semiconductor | is a semiconductor in which electrons are the majority charge carriers. |
| p-type semiconductor | is a semiconductor in which holes are the majority charge carriers. |
| Ampere | is that current which, if flowing in two, infinitely long parallel wires, of negligible cross-sectional area, one metre apart, in a vacuum, experiences a force of 2 x 10-7 N per metre. |
| Electromagnetic Induction | When a conductor cuts a magnetic flux an emf is induced. |
| Faraday's Law | states that the size of the induced emf is proportional to the rate of change of flux. |
| Lenz's Law | states that the direction of the induced emf is always such as to oppose the change producing it. |
| Magnetic Flux | is the product of Flux Density by Area. |
