self induction is called the inertia of electricity.why?
Self induction is that phenomenon in which a change in electric current in a coil produces an induced emf in the coil itself.
Now, it is also known as inertia of electricity as for if we were to change electric current through a current carrying coil it will tend to oppose any further change in its emf. This is similar to inertial behavior in mechanics were bodies in either rest or motion tend to oppose any change in their state. Here mass is the inertial property analogous to self inductance.
