Two coils A and B have 200 and 400 turns respectively. A current of 1 A in coil A causes a flux per turn of 10-3 Wb to link with A and a flux per turn of 0.8 × 10-3 Wb through B. The ratio of self-inductance of A and the mutual inductance of A and B is :
Using
Co efficient of self induction -
- wherein
Number of flux linkage with coil.
and
Co efficient of mutual induction -
- wherein
Number of turns in primary
Number of turns in secondary
current through primary.
