The capacitor calculator is an online tool that is used to calculate capacitance by taking permittivity, the distance between plates, and the area of plates as input.

A capacitor is a device that can store electric charges. The most common type of capacitor, shown below, is a parallel capacitor. In it type of capacitor, the plates of a capacitor are separated by an insulator.

Capacitance is the amount of electric charge which a capacitor can store.

The formula used to find capacitance is

**C = ****ε ****A/S**

In this equation:

** A **= the area on which plates overlap

** S** = distance between plates

** ε **= the permittivity of the conductor

The value of permittivity varies from conductor to conductor. To find capacitance with charge and potential difference, use our other capacitance calculator.

*Example:*

Calculate the capacitance of a capacitor that has ** 0.03 m^{2}** area of its plates separated by free space and the distance between the plates is

**Solution**:

**Step 1:** Identify values.

A = 0.03 m^{2}

S = 0.7 m

Permittivity of free space = 8.85418782 × 10^{-12} m^{-3} kg^{-1} s^{4} A^{2}

**Step 2: **Put the values in the capacitance formula.

C = ε A/S

= 8.85418782 × 10^{-12} ×0.03 / 0.7

= 0.38 F
