## Description

### Formula for calculating impedance XC

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

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

### Capacity calculation formula

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

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

### Formula for calculating the frequency

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

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