A diode is made from a small piece of semiconductor material, usually silicon, in which half is doped as a p region…
The valence and conduction bands in an n-type material are at slightly lower energy levels than the valence and conduction bands…
When you take a block of silicon and dope part of it with a trivalent impurity and the other part with…
Semiconductive materials do not conduct current well and are of limited value in their intrinsic state. This is because of the…
The valence shell of an atom represents a band of energy levels and that the valence electrons are confined to…
All materials are made up of atoms. These atoms contribute to the electrical properties of a material, including its ability to…
A dependent current source establishes a current, which is independent of the voltage across it, that is determined by the…
It can be quite useful to determine how a current entering two parallel resistors “divides” between them. Consider the circuit shown…
It can be quite useful to determine how a voltage appearing across two series resistors “divides” between them. Consider the…
It is not possible to combine independent current sources in series, since this would violate KCL. However, consider the parallel…
