complex impedance

- The expressing of an electrical impedance incorporating both its
__real number__and imaginary number components. Its formula is:, in which*Z = R + jX*is the impedance,*Z*is the resistance,*R*is the reactance, and*X*is the*j*__square____root__of -1. That is,*j*^{2}= -1.is expressed in ohms.*Z*
