Please help me to solve this problem!
What is the meaning of (2+j)ohms in the following question?
In a TT system, 3 phase, 4 wire symmetrical supply system, loads of 2 ohms, (2 + j) ohms and (1 ¡V j) ohms are connected in star in red, yellow and blue phases. The line voltage is 380 volts. If the neutral conductor OO¡¦ is open-circuited, find (i) the potential of the load star-point with respect to earth; (ii) the voltage across the loads; and (iii) the load currents in the three phases.
