The Townsend discharge is a gas ionization process where free electrons, accelerated by a sufficiently strong electric field, give rise to electrical ... more

The magnetic field in the volume of a long, thin loop of wire, wrapped around a metallic core (solenoid) when an electric current is passed through it, ... more

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how ... more

Generated at the center of a circular wire by the electric current, related to the electric current and the distance from the wire to center of the circle.

The force created on a straight stationary wire, carrying elecric current, placed in a magnetic field

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried ... more

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

The electric power produced by an electric current “ I “ passing through an electric potential (voltage) difference of “ V “
