Inductance is the property by which a change in current in a conductor induces a voltage both in the conductor itself and nearby inductors, the latter being the basis upon which transformers operate. Discrete inductors are also available that have many applications including filtering and energy storage.

Potential problems with disconnecting resistive load from transformer
The purely resistive load has no inductance so I wouldn't have a voltage spike, but the transformer has inductance. … I feel like this wouldn't change anything because the inductance of the primary coil will also be higher if the step down voltage is higher. …

Using MOV to protect device for heater element
Considering the only inductance I have is from the copper wire which ends up being somewhere around 50 microhenries and using a zero crossing ssr, I feel like the overvoltage will be negigible but I am …
