    +rep for just confirming if i'm right in a science problem

    +rep for correcting me pls lol

    What is the current in an electric stove element that creates 150J of heat at 240V over a 5 minute period?

    G: 150J (E), 240V (V), and 5m (300s) (t)

    R: Using the equation for current, I=Q/T, I know that I have the variable t, which is 300s, but not the others.
    However, I can rearrange the equation of V=E/Q to Q=E/V to figure out my variable Q, my last variable needed to find the current (I)

    A/S: Q=150/250
    = 0.625C

    I=0.625/300
    = 2.083x10^-03

    S: Therefore the current is 2.083x10^03.






    The number does not look right at all but can someone tell if I'm doing anything wrong?
