Question

Define self Inductance? Write its SI unit?

Answer 1

Hey !!

Self inductance is the property by which an opposing induced emf is produced a change in current, or magnetic flux, linked with the coil.

                                            (OR)

Self-inductance of a coil is numerically equal to the flux linked with the coil when the current through the coil is 1 A.

                                            (OR)

Self-inductance of a coil is equal to the induced emf developed in the coil when the rate of change of current in the coil is one ampere per second.

S.I Unit of self-inductance is ''HENRY''

NOTE :- I have provided you with the 3 definitions of self-inductance you can choose any one of them.

Good luck !!

Answer 2

Answer:

When the magnetic flux of the coil, which is linked to the coil, changes or the current in the coil changes, self-inductance of the coil is defined as the phenomenon that causes an emf to be induced in the coil.

                                               or

When the magnetic flux of the coil, which is coupled to the coil, changes or the current in the coil changes, self-inductance of the coil is described as the phenomena that causes an emf to be induced in the coil

The unit of self-inductance is  Ampere or Weber or Henry 'H'.
