نقطة واحدة Which of the following statement regarding an ideal single-phase transformer is incorrect? Transformer is having a turn ratio of 1: 2 and drawing a current of 10 A * ?from 200 V AC supply is incorrect Its rating is 2 kVA O Its secondary current is 20 A Its secondary voltage is 400 V O It's a step-up transformer ösals äbäi For a transformer with primary turns 400, secondary turns 100, if 20A current is flowing through primary, we will get 80A at secondary 40A at secondary O 5A at secondary 800A at secondary O
