summary
● Inductance is the ability to store energy in a magnetic field.
● The unit for measuring inductance is the henry (H).
● The letter L represents inductance.
● Inductors are devices designed to have specific inductances.
● The symbol for fixed inductance is
● A time constant is the time required for current to increase to 63.2% or decrease to 36.8% of the maxi- mum current.
● A time constant can be determined by the formula:
It takes five time constants to fully build up or col- lapse the magnetic field of an inductor.
