Text Solution

Verified by Experts
The correct answer is:
C
The self-inductance of a coil is defined as the ratio of the magnetic flux linkage to the current flowing through the coil. Its unit is the henry (H).
In SI units, 1 henry is defined as the inductance that produces an electromotive force of 1 volt when the current through it changes at the rate of 1 ampere per second.
Therefore, the unit of self inductance is the henry (H), which corresponds to Option C.
