There is no code rule designation which side that the wire colours are terminated on. I always use red on the left and black on the right when connecting to a distribution panel.

How do you read ladder diagrams?

You start at the top left of the print and proceed down the page reading from left to right. Usually the schematic is laid out in the sequence of operation.


What does a ladder diagram for a flashlight look like?

In North America the diagram will have a left and right supply rail. The rungs are between these rails in a horizontal position. Usually the voltage supply is on the left and return to source is on the right. The rung will consist of a switch in series with a lamp drawn from the left rail to the right rail. That's it. In European countries the rails are top to bottom. The rungs are between these rails in a vertical position. Usually the voltage supply is on the top rail and the return to source is on the bottom rail. The rung will consist of a switch in series with a lamp drawn from the top rail to the bottom rail.


What color should the wires be in a 120v system?

It depends. In a typical US residence with 120/240v single-phase power, the ground wire will be green, the neutral will be white, and the hot conductor will be either black or red depending on which phase it is connected to. Odd numbered breakers (1,3,5, etc.) are black, and even numbered breakers are red. You will measure 120v from black to white, also 120v from red to white, but 240v from black to red. In a commercial building with 3-phase 120/208 power, ground and neutral are the same color, but there are 3 hot colors - black (a-phase) red (b-phase) and blue (c-phase). As you run down a line of breakers from top to bottom they will be wired: black red blue black red blue etc. You will measure 120v from any of the 3 hot colors to white (neutral) but 208v from black to red, red to blue and blue to black.

To separate stereo audio signal from mono audio signal how can you do that?

If you have a mono signal then all stereo parts are gone and you really cannot get them back. The other way round is possible. You can add the left hand channel to the right hand channel and you get mono. like the guy said just reverse the left channel to right and right to left it will create a reveresed sound A.K.A mono. but why would you want to switch anyway? stereo is the peak of all speaker systems.
