In the power system of Fig. 1.5, \(\mathbf{E}_{\mathbf{1}}=200 \angle-30^{\circ} \mathrm{V}, \mathbf{E}_{2}=200 \angle 0^{\circ} V, \mathbf{Z}=j 5 \Omega\). Which one of the following choices is true?

1) The first electric machine is generating reactive power, and the second electric machine is consuming reactive power. Moreover, the first and the second electric machines are working as a generator and a motor, respectively.

2) The first electric machine is consuming reactive power, and the second electric machine is generating reactive power. Moreover, the first and the second electric machines are working as a motor and a generator, respectively.

3) Both electric machines are generating equal reactive power which is consumed by the reactance of the line. Moreover, the first and the second electric machines are working as a generator and a motor, respectively.

4) Both electric machines are generating equal reactive power which is consumed by the reactance of the line. Moreover, the first and the second electric machines are working as a motor and a generator, respectively.
