    Hi guys I have question please

    is RC circuit has a lower frequency(cut off frequency) Wc = 1 /RC rad/s
    or that only applies to low pass filter lower frequency am kinda confused

    also is 1/ RC in rad/s but if I want the duct off frequency in terms of herts then I would use the formula 1/2*pi*f0

    I need fully explanation pleaase
    thanks

    duct = the cut off frequency -3dB which is in another word the lower frequency Wc
    thanks anyway

    You can build an RC high-pass filter (resistor to ground) or a low-pass filter (capacitor to ground). In either case the -3dB corner frequency is Wc = 1/RC or Fc = 1/2\piRC.
