6 FAQs about [After the capacitor is connected]
What is a capacitor connection?
Circuit Connections in Capacitors - In a circuit, a Capacitor can be connected in series or in parallel fashion. If a set of capacitors were connected in a circuit, the type of capacitor connection deals with the voltage and current values in that network.

If a set of capacitors were connected in a circuit, the type of capacitor connection deals with the voltage and current values in that network. Let us observe what happens, when few Capacitors are connected in Series. Let us consider three capacitors with different values, as shown in the figure below.
What happens if two capacitors are connected in parallel?

When two or more capacitors are connected in parallel, the circuit still behaves as a single capacitor, but the total capacitance increases. Figure shows the equivalent circuit of the total capacitance in a parallel capacitor circuit.
Why does a series capacitor have a Q?
This occurs due to the conservation of charge in the circuit. When a charge Q in a series circuit is removed from a plate of the first capacitor (which we denote as − Q), it must be placed on a plate of the second capacitor (which we denote as + Q), and so on.
