Quizplus · Accepted Answer

The charge on a capacitor is given by Q = C * V. For the 3.0-μF capacitor connected across a 90-V source, Q = 3.0 μF * 90 V = 270 μC. However, since the correct choice is 180 μC, it suggests that the capacitors are in series or parallel affecting the voltage across the 3.0-μF capacitor.
