You build a transformer with 100 turns of wire on side 1, and 500 turns on side 2. A) If you put a voltage of 100 V (AC) on side 1, what voltage would you get on side 2? B) If you put a voltage of 100 V (AC) on side 1 with a current of 1 Amp (AC), what current would you get on side 2? C) If you put 100 V of DC voltage on side 1, what voltage would you get on side 2?

summary : This problem is based on using transformer turns ratio . For the convenience of understand represented side 1 and 2 as primary side and secondary side

we give DC as input on primary. its acts a short circuit in secondary due to change rate of current with respect to time is zero hence di/dt is zero and so transformer will burn or damage
