When an ____ flows through a ____ inductor, the value of the current is perpetually ____, so producing a ____ emf at every instant.If current changes in such a coil, an emf will be induced in the coil, to oppose the change. This self induced emf provides the only ____ to current flow. If the current is ____, the emf will ____ the supply voltage to limit the rate of increase, and if decreasing, will try to keep the ____. The unit of self inductance is the ____ (symbol H). The induced emf depends upon the rate of change of current.
