in which wire in an ac housing circuit is the switch introduced to operate the lights?
Answers
First off, it is not called an AC housing circuit, but by placing the abbreviation AC in front of the word housing, this confuses the reader as to what is contained inside the box.
A housing is a container for something.
In the case of English, a home is a place where people live, but the actual structure is called a dwelling, and the general act of living there is called housing.
So, it could be written as ‘a household electric circuit’ since by definition, the household typically has ac power that goes through the wires.
Exceptions are Marine, RV and Automobile usage.
An introduction is what happens between people.
A mechanical thing such as a switch does not get ‘introduced’, it is placed in the circuit somewhere along the loop of current.
Where that break is placed is important, however, due to the electrocution of a person years ago, when a socket was connected improperly, and the outer shell of the lamp was exposed through a break in the lamp holder, and the insulation allowed the screw part of the bulb to be touched by a homeowner.
The lamp was placed on a cord that was dangling above a wash basin. It had water in it. The resident reached to turn on the light but touched the side of the lamp where the socket had the insulation broken. The lady was instantly electrocuted, and froze as the electricity ran through her to the water in the tub.
The police found her next to the basin.
This is the reason that a particular wire is used, to break the circuit, if the proper wire had been used , then the outer screw of the light bulb would not have been energized with the potential to kill. It was connected wrong, so the problem was solved, by having the right connection, stopping the current flow, and the shell of the lamp(the screw part) connected to the return conductor.
So, a better way to write the question, would be to write the circumstances before the question, then the question itself.
As an example:
In a household lighting circuit, which wire has the switch connected to it?
And the pictorial representation, to help describe the question.
In an AC circuit meant for wiring up lighting for an apartment, it is usually a three wire system consisting of a live, neutral and the earth wire.
The live wire should always be connected to the switch so that you can toggle it to switch your light on or off.
