Formula for calculating reactance XC

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

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

Capacity calculation formula

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

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