    The impedance (AC resistance) of 1km wire

    10mm 1.91 ohms

    6mm 3.3 ohms

    4mm 4.95 ohms

    1.5mm 13.3 ohms

    (1760watt/110volts)=16amp load

    10AWG = 2.5mm at 100 metres length gives a voltage drop of 6.23 volts at 19 amps This gives 2161 watts for a 2200 watt hotplate or 98%
