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…
Dependent Sources An ideal source, either voltage or current, whose value depends upon some parameter (usually a voltage or current)…
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…
Combining Independent Sources An inspection of the KVL equations for a series circuit shows that the order in which elements …
Combining Resistors Relatively complicated resistor combinations can be replaced by a single equivalent resistor whenever we are not specifically interested…
