Calculators and formulas for calculating the cutoff frequency of a coil and a resistor
This function can be used to calculate the cutoff frequency of a coil and a resistor, or the inductance or the resistance. Two of the values must be known in order to calculate the third.

\(\displaystyle R\) Resistance
\(\displaystyle L\) Induktivität
\(\displaystyle f \) Grenzfrequenz
The resistance is calculated according to the following formula. The frequency \(\displaystyle f \) and the inductance \(\displaystyle L\) must be known.
\(\displaystyle R=2 · π · f · L \)
The inductance is calculated using the following formula. The frequency \(\displaystyle f \) and the resistance \(\displaystyle R \) must be known.
\(\displaystyle L=\frac{R}{2 · π · f }\)
The frequency is calculated using the following formula. The resistance \(\displaystyle R \) and the inductance \(\displaystyle L \) must be known.
\(\displaystyle f=\frac{R}{2 · π · L }\)
