Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. The term complex impedance may be ... more

First proposed by Clement D. Child in 1911, Child’s law states that the space-charge limited current (SCLC) in a ... more

The drift velocity is the average velocity that a particle, such as an electron, attains in a material due to an electric field. It can also be referred to ... more

Alternating current can be described mathematically as a function of time, angular frequency and peak current

In electrical and electronic systems, reactance is the opposition of a circuit element to a change of electric current or voltage, due to that ... more
