Far away from a magnet, its magnetic field is almost always described (to a good approximation) by a dipole field characterized by its total magnetic ... more
A magnetic dipole is a closed circulation of electric current. A simple example of this is a single loop of wire with some constant current through ... more
The Aharonov–Bohm effect, sometimes called the Ehrenberg–Siday–Aharonov–Bohm effect, is a quantum mechanical phenomenon in which an electrically charged ... more
Alternating current voltage can be described mathematically as a function of time, angular frequency and peak voltage

Capacitance is the ability of a body to store an electrical charge. Any object that can be electrically charged exhibits capacitance. Concentric or ... more
A bipolar junction transistor (BJT or bipolar transistor) is a type of transistor that relies on the contact of two types of ... more
Tunnel ionization is a process in which electrons in an atom (or a molecule) pass through the potential barrier and escape from the atom (or molecule). In ... more
An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter ... more
