Calculator and formulas for calculating the impedance of a capacitor

On this page you can calculate the impedance of a capacitor, the capacitance or the corresponding frequency. Two of the values must be known to calculate the third.

The impedance can be calculated using the following formula. The frequency \(\displaystyle f \)and the capacity \(\displaystyle C \) must be known.

\(\displaystyle XC=\frac{1}{2 ·\ π · f · C }\)

The capacity is calculated according to the following formula. The frequency \(\displaystyle f \) and the impedance \(\displaystyle XC \) must be known.

\(\displaystyle C=\frac{1}{2 ·\ π · f · XC }\)

The frequency is calculated according to the following formula. The impedance \(\displaystyle XC \) and the capacity \(\displaystyle C \) must be known.

\(\displaystyle f=\frac{1}{2 ·\ π · XC · C }\)
