The necessity of a return wire in electrical distribution is fundamental for creating a closed loop that allows current to flow from the generating plant to the load. This wire is essential in high-power transmission systems, particularly in three-phase AC power systems, where it ensures that the current returning to the source is equal to the current supplied to the load, as dictated by Kirchhoff's law. The return wire not only completes the circuit but also plays a critical role in maintaining voltage levels across the load, facilitating efficient power transfer.
PREREQUISITESElectrical engineering students, professionals in power distribution, and anyone interested in understanding the principles of electrical circuit design and operation.
physicspriya said:i m an electrical student. can anybody clearly tell me why is a return wire provided from the generating plant to the load? does current flow through the return wire or is it simply meant to form a closed lop?
physicspriya said:so the concept of closed loop is met.Now my next question is does the return wire carry the same amount of current as the go wire?please explain this in detail. Thanks for responding to the previous question
