IMPEDENCE IN AN AC CIRCUIT IS
=VOLTAGE/CURRENT

Answer / koriya rajesh

impedance=sqrt(r^2+ X^2); where X=xl-xc

Answer / tamil

impedance is a combination of resistance and reactance (capacitive reactance or inductive reactance ) Z=R+jXC

Answer / naqash

impedance no formula

Answer / ibrahim

capacitance opposite impedance
impedence formula :Z=1/c

Answer / anil patel

Z=under root R^2+(Xl-Xc)^2
Z=I/V it`s unit is mho
