Where the constants a b and c depend on the values of the resistors and capacitors. February 03 2021 Scientist with beakers. Define the terms i cut-off voltage and ii threshold frequency in relation to the phenomenon of photoelectric effect.
The cutoff frequency is defined as when the voltage across the resistor and the voltage across the inductor or capacitor are equal this occurs when.
Where the constants a b and c depend on the values of the resistors and capacitors. Sometimes known as a break frequency or corner frequency a cutoff frequency is a term that is often used in electrical engineering and physics. This -3dB cutoff frequency calculator calculates the -3dB cutoff point of the frequency response of a circuit according to the formula fC1 2pRC. For a simple RC low pass filter cut-off 3dB point is defined as when the resistance is the same magnitude as the capacitive reactance.
