Inductance of a Coil and Self Inductance Tutorial

Web6 aug. 2024 · Where: L is the inductance in Henries, V L is the voltage across the coil and di/dt is the rate of change of current in Amperes per second, A/s. Inductance, L is actually a measure of an inductors “resistance” to the change of the current flowing through the circuit and the larger is its value in Henries, the lower will be the rate of current change. WebThen we can define mutual induction as the current flowing in one coil that induces a voltage in an adjacent coil. But mutual inductance can also be a bad thing as “stray” or “leakage” inductance from a coil can interfere with the operation of another adjacent component by means of electromagnetic induction, so some form of electrical screening …
