In the three-phase power system of Fig. 1.16, two balanced three-phase loads with the star and delta connections have been connected to a three-phase power supply. Calculate the line voltage of the loads for the following specifications:

\[
E_{r m s}=4 V, \mathbf{Z}_{\mathbf{1}}=j 2 \Omega, \mathbf{Z}_{\mathbf{2}}=(2+j 2) \Omega, \mathbf{Z}_{\mathbf{3}}=j 3 \Omega, \mathbf{Z}_{\mathbf{4}}=-j 6 \Omega
\]

1) \(2 \sqrt{3} \mathrm{~V}\)

2) \(\left(6 \angle 30^{\circ}ight) \mathrm{V}\)

3) \(6 \sqrt{3} \mathrm{~V}\)

4) \(\left(6 \sqrt{3} / 30^{\circ}ight) \mathrm{V}\)
