Electrical
Impedance
An AC putting a
voltage v on load z and running current I
Electrical
impedance means how much the circuit impedes the flow of
electric
current. It is the computation of opposition
to a
Alternating Current.
Electrical impedance is the similar to electrical
resistance;
the SI unit is the
ohm. The term
impedance was coined by Oliver Heaviside in July
1886.The inverse of Electrical Impedance is
Admittance. We Know that V=IR. On
substituting R with Z we get
V'=I'Z'=I'Z*e^jθ
Magnitude of the
impedance-Z-It works like a resistance , Impedance-Z',Current-
