    Answer:

    125 V

    Explanation:

    Given,

    Power ( P ) = 500 W

    Current ( I ) = 4 A

    To fine : –

    Potential difference ( V ) = ?

    Formula : –

    P = V I

    V = P / I

    = 500 / 4

    V = 125 V

    Therefore,

    the potential difference across the ends of the heating element is 125 V.
