# Series and Parallel Capacitance Calculator

Capacitors are essential components of electrical circuits. Capacitors store electrical energy in the form of an electric field. A capacitor essentially comprises two conducting parallel plates with a dielectric medium in between them. A dielectric is like an insulator but with a property of being polarizable.

### Properties of a capacitor

• A capacitor opposes a change in voltage.
• The current produced in a capacitor is leading the voltage; which means the current is 90 degrees ahead of the voltage across the capacitor.
• A capacitor is an ideal electrical element; this means theoretically it does not absorb or dissipat

### Applications of a capacitor

The property of a capacitor to store electrical energy in the form of voltage and its another property of producing leading current makes it useful in many electrical applications.

• During the generation of electricity, a small capacitor is connected at the end of the generator circuit to result in a leading power factor that is ideal for reducing power losses and producing better current waveform.
• In the transmission and receiving of radio signals, capacitors are used in filter circuits.
• In timer circuits or oscillatory circuits, capacitors are essential elements.
• Capacitors make a good choice for energy storage. For example, cars have huge inbuilt capacitors to power car audio system to provide required sound amplification.
• The two main aspects of the construction of a capacitor – the distance between the parallel plates and the dielectric used, enables capacitors to be used as mechanical sensors.
• Capacitors are also used for power conditioning and in rectifier circuits to convert AC to DC.

### Series and Parallel Capacitance Connections

Depending on the way their ends are connected, there are two basic types of capacitance circuits:

• Series Capacitance Circuits
• Parallel Capacitance Circuits

As we move ahead in this post, we shall understand the working, comparison, calculations involved and differences between these series circuits and parallel capacitance circuits.

### Series Capacitance Circuits

Two or more capacitances are said to be connected in series if they are connected end to end. When two capacitors are connected C1 and C2 in series, the net capacitance is equal to the inverse of the sum of the inverses of individual capacitors.

1/Cnet = 1 / C = 1 / C1 + 1 / C2

When capacitances are connected in series, the net capacitance of the circuit is lesser than the value of any of the capacitance in the circuit.

### Parallel Capacitance circuits

Two or more capacitors are said to be connected in parallel if all their positive polarities are connected to one end and all negative polarities are connected to the other end in a circuit.

In a parallel circuit, the current originating from the source or the total current will branch up at the junction where the positive polarities of capacitances meet and then flows in different quantity in each capacitor and then again combines together at the meeting point of the negative polarities junction and flow towards the origin.

When capacitances are connected in parallel, the net capacitance is the sum of all the capacitances connected in the circuit.

Cnet = C1 + C2

### Combination of Series and Parallel Capacitances

If in a circuit there are capacitors in series and parallel, then you have to solve the capacitors combination step by step considering whether they are in series or parallel with the neighboring ones and then arrive at the final capacitance of the circuit.
