[ri′tərn ‚wīr] (electricity) The ground wire, common wire, or negative wire of a direct-current power circuit.
What is a return in electrical?
ground return in Electrical Engineering
Ground return involves using the ground as a return conductor, which allows a single wire to be used to carry current between two points. … Ground return is the return path for an electrical circuit made by connections to ground at each end.
Is Neutral same as return?
The neutral is the return path back to earth after the electricity travels thru the load. ( light, motor, computer….) With no load, there is no potential (voltage) on the neutral under normal circumstances.
Is Return same as ground?
The ‘source’ of electrons is the point where they enter into the circuit. And the point where electrons leave an electrical circuit is called the ‘return’ or ‘ground. ‘ Since electrons always end up at the source when they complete the path of their circuit, we call that exit point ‘return. ‘
What is return supply in electricity?
Electricity always returns to the source of the power supply (a transformer or substation). … When electrical current returns to the power supply substation through a neutral conductor (a power line or wire), it is normal for a small amount of current to also flow through the earth.
Does neutral wire have power?
Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.
Can I tie the neutral and ground together?
No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.
What happens if neutral touches ground?
The neutral is always referenced to ground at one, and ONLY one, point. If you touch the neutral to ground anywhere else, you will create the aforementioned ground loop because the grounding system and the nuetral conductor are now wired in parallel, so they now carry equal magnitudes of current.
Where does return current flow?
Typically, the return current flow occurs through the ground plane or an adjacent signal trace. In effect, a given signal and its current return path form a basic current loop where the magnitude of the current flow in the loop and the area of the loop determine the magnitude of the Electromagnetic Interference (EMI).
Why does electricity need a return path?
Now electrons from high concentration region moves towards low concentration to complete the electrochemical reaction. The wires act as a path for the electrons. Hence the number of electrons entering and leaving are equal. So we need a return path for the electrons to flow.
What is a return signal?
signal-return circuit: A current-carrying return path from a load back to the signal source, i.e., the low side of the closed loop energy transfer circuit between a source-load pair. (
