A battery producing a constant voltage, V, is applied to an RC series electric circuit with resistance, R, and capacitance, C. Let I(t) be the current flowing in the circuit.
(a) Given that RI(t) + Q(t)/C = V, find a formula for the charge, Q(t), on the capacitor in terms of time t.
Q(t) =
(b) What is the behavior of the charge as time passes?
