electical supply

Three identical 0.5 inductors with neligible resistance (0 homs) are connected to a 380V, 50Hz, 3-phase, 4-wire power supply. Calculate:

1. the impedance of the inductor;

2. the phase volage while the inductors are connected in star;

3. the phase current while the inductors are connected in star;

4. the line current while the inductors are connected in star;

5. the neutral current while the inductors are connected in star;

6. the phase voltage while the inductors are connected in delta;

7. the phase current while the inductors are connected in delta;

8. the line current while the inductors are connected in delta;
