What is the return path of the current in case of the balanced loaded 3 phase electrical conductors?
That's correct. Can you explain why the neutral wire is necessary in 3 phase electrical systems?
Certainly. In 3 phase electrical systems, the neutral wire provides a return path for the unbalanced current in case one or two phases are overloaded or faulty. It also helps to balance the voltage between the three phases.
