एक ट्रांसफार्मर में, समान शिखर प्रवाह घनत्व (peak flux density) पर कुल कोर हानि 40 Hz पर 52 W और 60 Hz पर 90 W पाई जाती है। 50 Hz पर भँवर धारा हानि (eddy current loss) की गणना कीजिए।

In a single-phase transformer, the number of turns per volt is 8. The primary voltage is 110 V and the secondary voltage is 25 V. Determine the number of turns in the primary winding (N1) and secondary winding (N2).

Consider a 20 kVA, 2200/200 V, 50 Hz single-phase transformer. Test results are: OC Test: 220 V, 4.2 A, 150 W (LV side) SC Test: 88 V, 10 A, 366 W (HV side) Determine the voltage regulation at full load with 0.8 lagging power factor.
