    The ohms law states that he potential difference of a current carrying conductor is proportional to the current and the resistance is constant.

    therefore; mathematically; V = IR where V is the voltage, I is the current and R is the resistance in the conductor.

    Making I the subject we get I=V/R

    Therefore to get current we divide voltage by the resistance

    I = 120 : 60 = 2 Ampheres

    Therefore the current is 2 Ampheres
