The characteristic frequency of an RC circuit determines the frequency of signals through the circuit. It is pretty simple to calculate once you know the formula.
f = 1/ 2π × R × C
Where:
R - Resistance of the resistor;
C - Capacitance of the capacitor; and
f - Characteristic frequency.
So, All you have to do is determine the product of 2, π (3.14), the resistance, and capacitance. Then divide one by the product. Read more
