English: Because, Z_(g) Z_(g) was given r g + j x g, so its magnitude Z_(g)=√it is capital R √R g ² + it is it is capital, X it is also capital X capital X g ² , so that is why R_(L)=√ sorry magnitude of Z_(g) .
Telugu: ఎందుకంటే, Zg =R_(g) + jx_(g) గా ఇవ్వబడింది, కాబట్టి |Z_(g)|= అందుకే R_(L) =  = |Z_(g)|అవుతుంది.
