Expression for characteristic impedance Zₒ of a transmission line in terms of L and C the transmission line is: Correct Answer √(L/C)

For a low loss line, the real part of impedance and admittance, that is resistance and conductance must be very small compared to the complex part of admittance and impedance for maximum power transfer. HenceR < <ωL and G < < ωC, with this assumption, modifying the expression for characteristic impedance√(((R+jωL))/√(G+jωC)), the ratio reduces to √ (L/c).
