Question

A hydroelectric with 0.2 m radius coils has permanent magnets that immerse the coils in a magnetic field of 0.5 T. If the maximum torque that the turbines can produce is 750 Nm and it is sought to generate a maximum voltage of V = (1414.3 V) sin (wt) at an average rms power of 2x10 ^ 4 W. a) What maximum current the turbine should generate, b) how many turns should the coil have, c) what radius should the coil cable have? d) if it is to be transported at 50 kvrms, how many turns should the secondary inductor of the transformer have for each turn of the primary?
