This capacitance calculator evaluates the circuit's total capacitance, potential difference, and electrical charge for multiple capacitors connected either in series or in parallel.
Understand the Concept of Capacitance:
“The capability of a system to store energy in the form of electric charge is known as the capacitance of that system”.
- Capacitance is measured in Farads (F).
The capacitance depends on the capacitor and the dielectric material that is used in between the plates. So, we say that a capacitor is utilized as a device to store electric charge. This amount of electrical charge that a capacitor can store is determined by the capacitor calculator.
A capacitor consists of two plates of conducting material separated by insulating material referred to as dielectric.
Capacitance Calculation Formula:
This ratio of change in electric charge to the electric potential of the system is determined by the capacitance calculator. For manual calculations, the following formula helps you to understand how to find capacitance:
$$ C = \frac{εA}{s} $$
Where:
- C is a capacitance
- ε is a permittivity
- A is a parallel plate area
- d is the distance between two conductive plates
By formula, it is determined that the value of C is directly proportional to the area and inversely to the distance between the conducting plates.
By default, the capacitor calculator uses the permittivity value for a vacuum that is approximately 0.000000000008854 F/m but this can be changeable. Look at the table below that will help you to understand how different materials have different permittivity values, affecting the capacitance of capacitors.
Materials | Unit (Farads per meter) |
---|---|
Air | 8.85 x 10^(-12) F/m |
Vacuum | 8.85 x 10^(-12) F/m |
Glass | 4 - 7 F/m |
Water | 80 F/m |
Ceramic | 50 - 120 F/m |
Teflon | 2.0 - 2.1 F/m |
Polyethylene | 2.2 - 2.4 F/m |
Our capacitors in parallel calculator are used to calculate capacitance of any capacitor, including parallel and series plate capacitors.
Series Circuit of Capacitor:
In a series circuit of capacitors, the reciprocal of the total capacitance equals the sum of the reciprocals of individual capacitances.
1/Ctotal = 1/C1 + 1/C2 + …
Parallel Circuit of Capacitor:
In a parallel circuit of capacitors, the total capacitance is the sum of individual capacitances.
Ctotal = C1 + C2 + ...

Frequently Ask Questions:
Difference Between Capacitor and Capacitance?
The ability to store electric charge is known as capacitance and the energy storing device is known as capacitor.
What is the Working Principle of the Capacitor?
The working principle includes the accumulation of charges on the plates. The electric cloud is created when a voltage is applied across the plates that cause the negative and positive charges to accumulate on the respective field.
What is Permittivity (ε) in Capacitance?
Permittivity is a term that determines the material’s capacity to store electric energy. The capacitance calculator evaluates how permittivity substance can affect to accumulated charges on the capacitor plate.
