Question

A 12 µF capacitor is connected in series with a 4 µF capacitor, and the combination is connected across a 6 V power supply. What is the charge on the 12 µF capacitor?

Answer 1

The charge on the 12 µF capacitor can be calculated using the formula Q = CV, where Q is the charge, C is the capacitance, and V is the voltage. In this case, the capacitance of the 12 µF capacitor is 12 µF and the voltage across the combination of capacitors is 6 V. Therefore, the charge on the 12 µF capacitor is 72 µC.
