Question

Self-inductance of the conductor is one of the reasons for :

A.

Skin effect      

B.

Ferranti effect

C.

Stroboscopic effect    

D.

Corona effect

Answer ( Option A)

Skin effect      

Solution

High frequency also gives high inductive  reactance which causes the current to flow outer surface of conductor is known as the skin effect,  which is simply a consequence of self inductance.

This effect, which oppose the flow of current is most  pronounced along the center-line of a conductor and is caused by proximity to adjacent current flow.
