    The battery will do work equal to the potential difference times charge. So 1573= Q 12

    Q=131 C

    In Direct Current situations:

    Volts x Amps = Watts = Joules/second

    Amps = I in Coulombs/second (C/s)

    12I = 1573 J/Time <= one equation but 2 unknowns = current = I and t = Time

    Can not numerically solve for C => need to know either I or t
