A transformer has 25 turns in the primary coil and 200 turns in the secondary coil. If 12 V is connected to the primary coil and a 20-Ù device is connected to the secondary coil, calculate the current in Amperes passing through the device

    The voltage applied to the secondary circuit will be 12*(200/25) = 96 volts

    Use ohms law for the device current.
