    Answer:

    4.17 A

    Explanation:

    Charge is given as the product of current and time hence expressed as

    Q=It

    Where Q is charge in Cuolombs, I is current in Amperes and t is time in seconds

    Making current, I the subject of the formula then

    I=Q/t

    Conversion

    1 minute has 60 seconds

    2 minutes will have 2*60=120 seconds

    Substituting 120 s for t and 500 C for Q then

    I=500÷120=4.1666666666666666666666666666666666666666

    Rounded off, current is approximately 4.17A
