    PLEASE HELP The charge on an electrons is -1.6x10 to the -19C. How many electrons are passing a given point in an electric circuit each second will give rise to a current of 4.0A?

    My answer is:

    Q=Ixt

    -1.6x10^-19=4.0xt

    4.0xt=-1.6x10^-19

    =-1.6x10^-19x-6.2 divide by 4.0

    =2.48x10^-19 or 2.5x10^-19
