    Answer: current I = 0.5 A

    Explanation:

    Given that the

    Potential difference V = 10V

    Resistance R = 20 ohms

    According to ohms law

    V = IR

    Where

    V = potential difference

    I = current

    R = resistance

    Make I the subject of formula

    I = V/R

    I = 10/20

    I = 0.5 Ampere
