Cut-off Frequency in AC Circuits Formulas

A Cut-off Frequency is a boundary in a system’s frequency response at which energy flowing through the system begins to be reduced rather than passing through. And is denoted by f_c. Cut-off Frequency is usually measured using the Hertz for Frequency. Note that the value of Cut-off Frequency is always negative.
