Answer / sindhu

the ratio of voltage/current in case of ac supply is known
as impedance.
z=r+j(xl-xc)
where xland xc are inductive and capacitive reactance
respectively.

Answer / shubhangi tyagi

impedence is the total opposition to the flow of current in ac circuit which acts due to resistor,inductor,capacitor

Answer / maya

real part of impedance is resistance&imaginary part of
impedance is resonance z=r+(xl-xc)i

Answer / sreejith

Impedance can be mentioned as Z. That is Z=square root of
(R^2+L^2) or Z= r+j(Xl-Xc)

Answer / anjali

current in an electric circuit

Answer / ramnath

Between inductive and capactive reactance respectively

Answer / harinath reddy
