A step-up transformer has a coil with 100 turns and a coil with 10000 turns. If the input voltage is 12.0 kV, the input current is 10.0 A, and the output voltage is 1200 kV, then what is the output current

  • Science 30 -

    power is the same on each side

    12KV*10A=1200KV*I

    solve for current I
