![A series circuit has a capacitor of 0.25 x 10 F, a resistor of 5 x 1032, and an inductor of 1 H. The initial charge on the capacitor is
zero. If a 3-volt battery is connected to the circuit and the circuit is closed at t = 0, determine the charge on the capacitor at t = 0.001
seconds, at t = 0.01 seconds, and at any time t. Also determine the limiting charge ast → ∞.
Enter the exact answer with a < b.
The charge at any time is given by the formula Q(t) = (Aeat + Be + C) x 10-6 coulombs, where
