Unfortunately inductance is usually not a friend in these ... I briefly light up a nixie tube with a big ‘ole coil and a 9V battery. The demonstration is meant to show that inductors really ...

[Apexys] is performing some experiments with switched-mode power supplies and needed to compare the inductance of the coils he was using. His multimeter doesn’t have an inductance testing ...

If the coil C1 is paired with C3, an emf 0.7ε is induced in it, for the same rate of drop in the current through C1 as ...
