An uncharged 5.0-µF capacitor and a resistor are connected in series to a 12-V battery and an open switch to form a simple RC circuit. The switch is closed at t = 0 s. The time constant of the circuit is 4.0 s.
-Determine the maximum charge on the capacitor.

Question

Quizplus · Accepted Answer

The maximum charge on the capacitor is given by Q = CV, where C is the capacitance and V is the voltage across the capacitor. In this case, C = 5.0 µF and V = 12 V, so Q = (5.0 µF)(12 V) = 6.0 × 10^-5 C.
