Given the system in Q$4.,$ for a line$-$to$-$line $($b$-$c$)$ fault at $\backslash (\backslash$mathbf$\{80\backslash \%\}\backslash )$ of the line$-$section $\backslash (\backslash$mathbf$\{$A B$\}\backslash ),$ calculate appropriate relaying voltages and currents at bus $\backslash (\backslash$mathbf$\{$A$\}\backslash ).$ Assume that the system positive sequence and negative sequence impedance on the left side of bus $\backslash ($ A $\backslash )$ is $\backslash ((\backslash$mathbf$\{1\}+\backslash$mathbf$\{$j $10\})\backslash$Omega $\backslash ).$
