WebThe magnetic circuit's flux that does not interlink both windings is the leakage flux corresponding to primary leakage inductance L P σ and secondary leakage inductance L S σ.Referring to Fig. 1, these leakage inductances are defined in terms of transformer winding open-circuit inductances and associated coupling coefficient or coupling factor .. … WebSelf-inductance does not depend upon current flowing or change in current flowing and temperature but it depends upon: Number of turns ( N ) Area of cross-section ( A ) Permeability of medium (μ o ). Thus the self-inductance of a coil can be changed by the number of turns per unit length of the coil. Hence option 2 is correct.
