A turbine of a hydroelectric installation delivers 1,500 hp of mechanical energy to a generator. The generator then converts 80.0% of the mechanical energy into electrical energy. If the terminal potential difference of the generator is 2070 V, what current does it deliver (in A)?

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

unbalanced force
