The primary coil of an ideal transformer has 100 turns and the secondary coil has 600 turns. Then

The primary coil of a transformer has 100 turns and the secondary coil has 300 turns. If the peak value of the alternating emf applied to the primary coil 150v, what is the peakvalue of the alternating emf obtained across the secondary coil?

The primary coil of a transformer has 800 turns and the secondary coil has 8 turns. I connected to a 220 V as supply. What will be the output voltage?

A generator supplies 100 V to the primary - coil of a transformer of 50 turns.If the secondary coil has 500 turns, then the secondary voltage is
