NOTATION

: The electromotive force of self-induction is the action of the field that arises when one's own current changes.
: Inductance is the ability of a conductor to create a magnetic field when current passes.
: Change in current strength - the amount of change in current over the time in question.
: Time interval - the duration of the process under consideration.
: A period is the time of one complete repetition of a process.
: Electrical capacity is the ability of a conductor or capacitor to accumulate charge.
: Inductive reactance is the resistance of the coil to alternating current.
: Frequency is the number of repetitions of a process per unit of time.
: Magnetic flux is a measure of the magnetic field passing through a surface.
: Current strength is the charge passing through the cross section of a conductor per unit time.
