RC Circuit - Complex Impedance

Complex Impedance

The complex impedance, ZC (in ohms) of a capacitor with capacitance C (in farads) is

The complex frequency s is, in general, a complex number,

where

  • j represents the imaginary unit:
  • is the exponential decay constant (in radians per second), and
  • is the sinusoidal angular frequency (also in radians per second).

Famous quotes containing the word complex:

    “Power is not an institution, and not a structure; neither is it a certain strength we are endowed with; it is the name that one attributes to a complex strategical situation in a particular society.”
    —Michel Foucault (1926–1984)
