Answer:
1) N = 200 turns
2) P = 15 Watt
Step by step explanation:
1) The number of turns is directly proportional to the potential difference in the coil for a transformer.
Therefore, .
Where is the number of turns in the secondary coil, is the number of turns in the primary coil, is the potential difference in the secondary coil and is the potential difference in the primary coil.
Hence, turns.
2) P = I*V
P = 300mA * 50V = 15 W
