If the current in a wire of a CD player is 5.00 mA, how long would it take for 2.00 C of charge to pass through a cross-sectional area of this wire?

one ampere is one Coulomb of charge per second

time = charge / current
Cu = I * T.
T = Cu/I = 2/5*10^-3 = ----seconds.

t =
I=Q/t
T= Q/I => 2.00/5.00= 0.4s
monkey
Cu = I * T
T = Cu / I = 2 / 5 * 10^{3}

Time = 400 seconds
