Introducing Series and Parallel Capacitors

For electronics beginners, capacitors might be confusing. Knowing how they work in series and parallel is crucial.

Capacitors in series reduce capacitance. Putting two 10 uF capacitors in series yields 5 uF. Series splits the voltage across each capacitor. Each cap in succession sees 5V from a 10V supply. Because capacitance depends on voltage, it halves.

The opposite occurs simultaneously. Capacitance rises when voltage holds steady. Because both caps share 10V, two 10 uF caps in parallel provide 20 uF. Power supplies benefit from parallel storage at the same voltage.

Series caps are ideal for high-voltage applications because they divide voltage. Parallel handles more current due to many pathways. Series caps are good for high-voltage filters, whereas parallel is better for decoupling circuits with larger current.

Choice depends on needs. Remember that series divides, reducing capacitance, while parallel combines, increasing it. Capacitors in series and parallel make sense after you understand these basics.

Compute Equivalent Capacitance for Series Capacitors

You want to link capacitors? Don’t worry—calculating series capacitor equivalent capacitance is easy.

A series capacitor circuit?

In a series capacitor circuit, the negative terminal of one capacitor connects to the positive terminal of the next. Each capacitor receives the same current.

How to calculate equivalent capacitance?

It’s simple. Just sum the capacitances. Three 10 uF capacitors in series provide an equivalent capacitance of 30 uF. The basic formula:

Ceq = C1 + C2 + C3… (where C1, C2, C3 are the individual capacitances)

Total series circuit voltage is sum of capacitor voltages.

Each capacitor has the same current.

Why series capacitors?

A few benefits of wiring capacitors in series:

You can increase the total voltage rating. Using lower voltage rated capacitors in series increases overall voltages since each capacitor divides the voltage. It may save money. As lower voltage capacitors are cheaper, series combinations can save money.

Space restrictions. Some high voltage capacitors are too large to utilize, so a series of lower voltage units is needed. Lower total capacitance and current handling are drawbacks of series capacitors. Series capacitors are useful for many applications due to their benefits. Try it—you’ll be a capacitance calculator in no time!

Finding Parallel Capacitors’ Equivalent Capacitance

Parallel capacitors add capacitance. The combination has a higher capacitance than any individual capacitor.

The equivalent capacitance (Ceq) of parallel capacitors is calculated by adding their capacitance values. For instance, the equivalent capacitance of three 10 μF capacitors in parallel is:

C1+C2+C3 = Ceq

= 10 μF + 10 μF + 10 μF

= 30 μF

Parallel capacitors have the same voltage. However, the parallel combination’s current equals the sum of each capacitor’s current. The total current increases with more parallel capacitors.

Parallel capacitors have advantages:

Total capacitance rises. More parallel capacitors provide more capacitance than any single capacitor.

It lowers equivalent series resistance. Multiple current routes reduce resistance. Thus, higher-frequency waves pass through more easily.

It boosts dependability. One capacitor can fail or become detached, but the others will continue work with a decreased capacitance.

•It supports different-voltage capacitors. Parallel works as long as each capacitor is rated for the applied voltage.

There’s less voltage demand on each capacitor. Capacitors receive a fraction of the applied voltage since the voltage is split.

Parallel capacitors are used for power supply filtering and energy storage. Understanding the simple equivalent capacitance calculation lets you size a parallel capacitor network.

Voltage, Current, and Charge in Series vs. Parallel

Capacitors can be connected in series or parallel. Their arrangement affects your circuit’s voltage, current, and capacitance.


Voltage splits between series capacitors. Two 10V capacitors in series have 5V apiece. Each parallel capacitor gets full voltage. Both 10V capacitors would get Full 10V.


The same current flows through each capacitor in series. But parallel current builds up. Two parallel 10V capacitors carrying 1A each total 2A. More parallel capacitors increase current capacity.


In series, capacitance decreases. Two 10F capacitors in series have 5F capacitance. In parallel, the capacitors’ capacitance increases to 20F.


Total charge (Q) is constant in series and parallel. Each capacitor stores less charge in series. Our 10F series capacitors held 5C each. Each capacitor could store 10C in parallel.

As you can see, capacitor arrangement affects circuit performance. Choosing a series or parallel arrangement can help you limit current, boost voltage tolerance, or maximize capacitance. The possibilities are unlimited, so grab your breadboard and experiment!

Actual Uses and Considerations

After getting capacitors, what next? How are they connected for optimal performance and values? Capacitors are usually connected in series or parallel. Each setup has merits and cons, so pick one that fits your application.

SerieS Configuration

Connecting capacitors in series links their negative and positive terminals. Total capacitance reduces but voltage rating rises. Use this formula to compute series capacitor equivalent capacitance (Ce):

1/Ce = 1/C1+C2+C3…

The capacitors’ capacitance values are C1, C2, and C3.

When capacitance is less important and voltage is larger, series is advantageous. However, one capacitor failure breaks the circuit.

Configure Parallelly

All capacitor positive and negative terminals are linked in parallel. Total capacitance rises, but voltage remains constant. Add the capacitance values of parallel capacitors to obtain their equivalent capacitance (Ce):


Parallel circuits have larger capacitance and are more reliable because one capacitor failure does not break the circuit. Maximum voltage is limited by lowest-rated capacitor.

Many applications use series and parallel connections to obtain voltage and capacitance ratings. You can customize a capacitor bank with the proper setup! Understanding how capacitors work in a circuit will help you learn capacitance calculation.


You now comprehend series and parallel capacitors. Equivalent capacitance, voltage and current behavior in each configuration, and the benefits and cons of choosing one over the other for your project may be calculated. Although series capacitors are simpler, parallel capacitors offer more options. Next time you create a circuit, you’ll know how to choose capacitors. Enjoy your experiments and may capacitance be with you!
