Download Solution PDFConcept:
Impedance (Z) = \({1\over Admittance (Y)}\)
Z = R + jX
where, R = Resistance & X = Reactance
Y = G + jB
where, G = Conductance & B = Susceptance
Calculation:
Given, Y = 3 + j4
\(Z={1\over 3+j4}\)
\(Z={1\over 3+j4}\times{3-j4\over 3-j4}\)
\(Z={1\over 25}(3-j4)\)
Resistance, R = \(\frac{3}{25}\Omega\)
