In Question #39, what is the power input and output of the transformer?

39. A step-up transformer has 350 turns on the primary coil and 1500 turns on the secondary coil. The primary coil has a potential difference of 1 10 V across it. The current in the secondary circuit is 15.0 A. What is the current in the primary circuit? Iz = 15 A I = ? V, = 11OV N2 350 150D Primary Secondary using Transformation ratio I, = 64. 285 A N2 I , = N2 x Iz = 39. I 2 N N 1500 x 15A = 64. 285 A 350
