This is College Physics Answers with Shaun Dychko. A battery is connected to a bulb and there's 2.50 amps of current flowing, what amount of charge will flow through the circuit in half a second? So current is the amount of charge that flows divided by the amount of time it takes and so we can solve for Q by multiplying both sides by t so the charge then is the current multiplied by the time. So that's 2.5 amps times 0.5 seconds, which is 1.25 coulombs; the answer is (c).
