[ FAQS] What form of energy storage is an inductor?

The inductance is characterized by the current can not be mutated. The process of inductive energy storage is the process of the maximum current from zero to steady state. When the inductor current reaches maximum steady-state value. If no resistance (such as superconductors) sho... [more]
