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. Let us observe what happens, when few Capacitors are connected in Series.
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.
So it depends on the capacitor type. If it is a capacitor that can't handle the voltage or current, or the supply can't handle the current, something may get damaged. If cap is at different voltage, it will be a short circuit when connected and when it reaches supply voltage it will be an open circuit.
In fact, since capacitors simply add in parallel, in many circuits, capacitors are placed in parallel to increase the capacitance. For example, if a circuit designer wants 0.44µF in a certain part of the circuit, he may not have a 0.44µF capacitor or one may not exist.
With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
One important point to remember about capacitors that are connected together in a series configuration. The total circuit capacitance ( C T ) of any number of capacitors connected together in series will always be LESS than the value of …

Capacitance in AC Circuits – Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only. Like resistance, reactance is also measured in …
Ideally, a capacitor is made of two plates separated by an isolator. Consequently, ideally there is an open circuit there. If you connect the capacitor to a battery, …
Before handling capacitors or working on circuits where capacitors are used, it is a sensible precaution to ensure they have been discharged. Small capacitors can be discharged directly with a short circuit. …
