Calculations: Section $11\mathrm{.}2$ and $11\mathrm{.}3$ in the book will help you with the calculations.

a$.$ Assume a Y$-$connected $3$ phase balanced ac source with RBY sequence with $\backslash (\backslash$mathrm$\{$V$\}\_\{\backslash$mathrm$\{$rms$\}\}=18\backslash$mathrm$\{$~V$\}\backslash ).$ Tabulate the magnitude and phase angle of the individual phase and line voltages of the source in the Table $1.$

b$.$ This $3-$phase source is connected to a balanced $3$ phase $\backslash ($ Y $\backslash )-$connected resistive load of $\backslash (1\backslash$mathrm$\{$k$\}\backslash$Omega $\backslash )$ per phase $($refer to Fig. $1).$ Calculate and tabulate the line $($phase$)$ currents of the load in Table $2.$

c$.$ This $3-$phase source is connected to a balanced $3$ phase $\backslash (\backslash$Delta $\backslash )-$connected resistive load of $\backslash (1\backslash$mathrm$\{$k$\}\backslash$Omega $\backslash )$ per phase $($refer to Fig. $2).$ Calculate and tabulate the line and phase currents of the load in Table $3.$
