Question

(a) Define self-inductance of a coil and hence write the definition of  'Henry'.

(b) Write any two factors each on which the following depends :

(i) Self-inductance of a coil.

(ii) Mutual inductance of a pair, of coils.

(i) Its geometry (area and length of a coil)

(ii) Number of turns

(iii) Number of turns in each coil.

(iv) Nature of medium in the intervening space.

(c) Mutual inductance of a given pair of coils depends on

(i) Their geometries

(ii) Their distance of separation

(iii) Number of turns in each coil.

(iv) Nature of medium in the intervening space.
