Inductance: formulas and units of measurement

Note: n is the number of turns of the coil, Φ is the flux through one turn; nΦ - flux linkage. The connection is linear with constant inductance.

\mathcal{E}_{\text{си}}

The electromotive force of self-induction is the action of the field that arises when one's own current changes.

L

Inductance is the ability of a conductor to create a magnetic field when current passes.

\Delta I

Change in current strength - the amount of change in current over the time in question.

\Delta t

Time interval - the duration of the process under consideration.

T

A period is the time of one complete repetition of a process.

C

Electrical capacity is the ability of a conductor or capacitor to accumulate charge.

X_L

Inductive reactance is the resistance of the coil to alternating current.

\nu

Frequency is the number of repetitions of a process per unit of time.

n

The number of turns is the number of turns of conductor in the coil.

\Phi

Magnetic flux is a measure of the magnetic field passing through a surface.

I

Current strength is the charge passing through the cross section of a conductor per unit time.
