A 10-KVA, 50 Hz transformer was found to have an efficiency of 98% at full-load, 0.8 power factor lagging. It

A 10-KVA, 50 Hz transformer was found to have an efficiency of 98% at full-load, 0.8 power factor lagging. It was also found that the maximum efficiency was obtained at 85% full-load, at the same power factor. Determine the core loss P, copper loss at full load Pouf and the maximum efficiency of the transformer nmax at 0.8 power factor lagging? i. Enter P, (in W): (in W): cull ii. Enter P. iii. Enter nmax (in %): (correct to 4 decimal places) (correct to 4 decimal places) (correct to 4 decimal places) Please answer to 4 decimal places, for example 1.2345 Do not enter space before, between and after the numbers
