Lenz’s law /ˈlɛnts/ is a common way of understanding how electromagnetic circuits obey Newton’s third law and the conservation of energy. ... more

Is the peak energy stored in the circuit divided by the average energy dissipated in it per cycle at resonance, and is the inverse of fractional bandwidth

An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned ... more

The heat flow can be modelled by analogy to an electrical circuit where heat flow is represented by current, temperatures are represented by voltages, heat ... more

In mathematics, the Klein bottle is an example of a non-orientable surface, informally, it is a surface (a two-dimensional manifold) in which notions of ... more

The Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets ... more

Electromotive force, abbreviated emf (denoted ℰ and measured in volts) is the electrical intensity or “pressure” developed by a source of ... more

If a mole of ions goes into solution the charge through the external circuit depends on the number of moles or ions and the “Faraday constant” ... more

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