which physical quantity is khown as inertia of electricity? why..
Answers
Self induction of coil is the property by virtue of which it tends to maintain the magnetic flux linked with it and opposes any change in the flux by inducing current in it. This property of a coil is analogous to mechanical inertia that is why self induction is called inertia of electricity.

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.
