👍👍Inductance👍👍

Unit is Henrys, Symbol is H or L (depending on context). Inductance occurs in any piece of conducting material, but is wound into a coil to be useful.

An inductor stores a charge magnetically, and presents a low impedance to DC (theoretically zero), and a higher impedance to AC dependent on the value of inductance and the frequency.

In this respect it is the electrical opposite of a capacitor. Inductance is always a positive value. The symbol “Hy” is sometimes used in the US. There is no such symbol.
