How does a capacitor work?

An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.

What is the difference between a parallel capacitor and a series capacitor?

When capacitors are connected in parallel the total capacitance is equal to the sum of the single capacitances. When connected in series the reciprocal value of total capacitance is equal to the sum of reciprocal values of the single capacitances. When the capacitors are connected there is the same charge on each of them.

How do you know if a capacitor has a charge?

Charges on capacitors in series are equal to each other and in this case also equal to the total charge. Therefore the charge on the third capacitor is equal to the total charge. If we know the charge, we can evaluate the voltage on the third capacitor. Voltages on both capacitors connected in parallel are the same.
