A 20-$\mu$F capacitor is charged to 200 V and is then connected across a 1000-$\Omega$ resistor.What is the initial charge on the capacitor?
A)10 mC
B)5.6 mC
C)4.0 mC
D)8.0 mC
E)2.0 mC

Question

Quizplus · Accepted Answer

The initial charge on the capacitor can be calculated using the formula Q = CV, where Q is the charge in coulombs, C is the capacitance in farads, and V is the voltage in volts. Given a capacitance of 20 μF (which is 20 x 10^-6 F) and a voltage of 200 V, the initial charge Q = 20 x 10^-6 F * 200 V = 4 x 10^-3 C, or 4.0 mC.
