Formulas

E_{si} = L \frac{∣ Δ I ∣}{Δ t}

εsi = L|ΔI| /Δt

T = 2 π L C

T = 2π√(LC)

X_{L} = 2 π ν L

Xᴸ = 2πνL

Φ = L I

Φ = LI

NOTATION

$\mathcal{E}_{\text{si}}$: 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.
$\Phi$: 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.
