Explanations

Inductance

Inductance is a measure of the relationship between the current and the magnetic flux. The inductance of a circuit prevents changes in the current that passes a coil. The unit of inductance is the Henry (H) or alternatively Weber per Ampere. 1 H is in most cases a very high induction of which is used for example mH etc. instead.

Resistance

Resistance is a current limiting ability of an electrical circuit that which motstånde available in the circuit. Resistance is measured in ohms (Ω).

Time constant

A constant used in the calculations.

Reactance

Reactance is a term for a frequency-dependent electrical resistance that occurs in both capacitive and inductive form.

Angular frequency

Angular frequency can also be called rotational speed and is a measure of how much an object rotates around its center of rotation. Angular velocity is measured in SI units of radians per second (rad/s). Radians are a rewrite for degrees that facilitate mathematical calculations.
