RL cutoff frequency calculation
Calculator and formulas for calculating the cutoff frequency of a coil and a resistor
This function can be used to calculate the cut-off 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.
