Will the winding behavior consume more electricity when reforming the circuit?

When the circuit is reformed, the winding will form an inductance on the circuit, and this inductance will produce a rapid change of magnetic field and impedance current, but it will not consume electricity. In principle, electricity is not needed. However, considering that the line itself has a certain resistance, winding increases the length of the wire and has a certain power loss, but it is far from power consumption.

As for the winding behavior in circuit modification, it is generally located at the joint position, such as the end point of socket and lamp, which is not intentional, but it has certain effect.

1. Protect sockets and wires of subsequently connected electrical equipment. The coil forms an inductance after winding several times at the terminal position, which has a certain impedance effect on the suddenly changing current. In this way, after connecting electrical appliances, lightning strike and AC surge can be prevented to a certain extent, and the connected electrical appliances can be protected from damage while protecting the socket.

2. It is convenient for later circuit maintenance and power socket replacement. There is a saying that one more is good, and the circuit at home will inevitably go wrong and need to be repaired. The same is true for power sockets, switches and lamps. When replacing and repairing, it is likely to be necessary to cut off a section of the line. If it is not wound, it is likely that the line will not be reached, and there will be an extra interface problem when the extension line is extended again. With this winding coil, it is enough to stretch it a little. In addition, when the line is maintained, it is inevitable to pull the wire. In order to prevent all wires from entering the catheter, a few more turns can also prevent this from happening.

3, easy to install sockets and switches We know that sockets and switches are embedded in the wall. If the wires reserved in the wall can just be connected, it is difficult to install the socket and switch. If a piece of wire is reserved for winding, it is easy to connect the socket and switch, and of course, other devices are the same, so it is easy to connect.

General electricians will wind wires at the end when installing or transforming lines, which is the existence of the above three functions. However, don't think that electricians are walking around casually. There are some sayings in it. One of the most important requirements is that the winding should not be too long or too short. The general requirement is half the circumference of the box. If it is a type 86 box, the winding length is 86x4/2 = 172mm.
