Question

Example 8. A balanced, star-connected load is supplied
from a symmetrical 3-phase, 400 V system. The
current in each phase is 30 A and lags by 30° behind the voltage, Find: (i) the impedance in each phase ; (ii)
total power drawn. Draw the phasor diagram.​

Answer 1

Answer:

Explanation:

See there is a substance between two of them so the answer is nill

Answer 2

The impedance in each phase is 7.5 milliohm.

Explanation:

The impedance Z=I/V

Z=30/400

Z=0.075

Z=7.5 milliohm

The impedance is directly proportional to the current and indirectly proportional to the Voltage applied.
