If the number of turns per units length of a coils of solenoid is doubled , the self- inductance of the soleniod will

Self induction of a solenoid is

A coil is wound on a frame of rectangular cross - section. If all the linear dimensions of the frame are increased by a factor x and the number of turns per unit length of the coil remains the same, self - inductance of the coil increases by a factor of

A copper wire is wire is wound on a wooden frame, whose shape is that of an equilateral triangle.If the number of turns of the coil per units length of the frame the same, then the self inductance of the coil:

A coil is wound as a transformer of rectangular cross section. If all the linear dimension of the transformer are increased by a factor 2 and the number of turns per unit length of the coil remain the same, the self-inductance increased by a factor of

The unit of self inductance of a coil is

Self-inductance of a solenoid depend on-

When number of turns of a solenoid is doulbed, its self inductance becomes k time, where k =

For a solenoid keeping the turn density constant its length makes halved and its cross section radius is doubled then the inductance of the solenoid increased by :-
