For a process to be isothermal, any heat flow into or out of the system must occur slowly enough that the thermal equilibrium is maintained. In general, none of the three quantities are zero. We can see all these processes ...

Inductance
... The proportionality constant L is called the inductance of the device. It is a property of the device (geometry, windings) and does not depend on the current. Inductance is measured in units of “henrys”, where 1 henry = 1 volt-second/ampere. For circuit analysis, it is enough to know just the induct ...
