Flux loss can be minimized using ……… core.

Fill ups Eddy current can be reduced by using ……………..cores.

Statement (A) : Flux leakage in a transformer can be minimized by winding the primary and secondary coils one over the other. Statement (B) : Core of the transformer is made of soft iron

If mu_(1) and mu_(2) are the refractive indices of the materials of core and cladding of an optical fibre, then the loss of light due to its leakage can be minimized by having
