A 500 kVA transformer at a certain loading condition gives iron loss : Pi=2500 Watt and the copper loss : PCu=7500 Watt. If the maximum efficiency occurs at the same loading condition, the load on the transformer in kVA would be approximately: 

The maximum flux density in the core of a 250/3000-volts, 50-Hz single-phase Transformer is 1.2 Wb/m². If the e.m.f. per turn is 8 volt, then area of the core is _______m²

A coil A of 1200 turns and another coil B of 800 turns lie near each other so that 60% of flux produced in one links with the other. It is found that a current of 5A in coil A produces a flux of 0.25 mWb, while the same current in coil B produces a flux of 0.15 mWb. The value of mutual inductance is______H
