Nah. When you start admitting the things you are wrong about, carefully, completely, and politely, I'll think about it. For example, are you ready to admit that threads were not being selectively deleted, and that your faulty conclusion was based on your inability to use the search engine properly?

I'm sure this simple solution would make your life a lot easier -- not having me, or others, politely post questions that you utterly fail to address would be much less hardship on you, I expect.

Then why did you post a statement contradicting it, immediately after "reading" it?
Explain how a "return path" could possibly be negative. Quoting: IDW 316602
Why couldn't it be?
Voltage is just a potential difference, and although electrons flow from -ve to +ve it is represented as +ve to -ve. Effectively -ve is usually the "ground" or "common" of a circuit.
Whats a positive ground in a dc circuit, and whats the difference between a positive 'grounded' automobile and a negative grounded one. Quoting: IDW 316602
By your usual standards you should probably be claiming this is a mis-use of the word "ground", though as recent posts show you'd rather use the different usages to your wiggly advantage.
This particular use of "ground" is simply refering to what voltage (the -ve or +ve side of the circuit) is the "common rail" of the circuit. It doesn't change which direction electrons flow (-ve to +ve) or which direction it would be drawn (+ve to -ve). |

Alternating curent means what it says it is. With 60 cycle per second (htz) household current, the polarity reverses 60 times per second, meaning both leads carrying power are alternating both negative and positive .
None of my amplifiers have ever had the three wire system but it is clear you do not understand it at all.Amplifiers generally have a ac to dc converter as a power supply, but the output at the speaker terminals is alternating current that matches the frequency of the sound being reproduced. The color coding on the terminals is for PHASING only, and DO NOT indicate negative or positive.
The third wire connects the two channels of stereo amplifier to take advantage of the difference in potential between channels that would otherwise be wasted. Frequently a bass or 'center' speaker will be connected to both channels because bass is niether directional to the human ear nor part of the stereo 'image' anyway, and this third terminal just provides a seperate connection for it. You can accomplish precisely the same thing with any amplifier simply by connecting the black terminals (notice black IS NOT ground, this alternating current!), you had just better make sure you match impeadance or you'll have fried finals if you try to crank it up. I did this with my own Pioneer amplifier, which I purchased in 1982 and it is still working to this day ,in perfect order. In fact it is connected to this computer. |

There is a need in electrical circuits for a return path. It is common in certain circles to refer to this as "ground" as well.
The slang use of the term "ground" as the negative side of a dc circuit refers to the NEGATIVE SUPPLY SIDE. The negative IS NOT the return path,, that is the most common misconception about electricity that exists, proving youre nothing but a copy and paste no nothing blowhard.
Same difference. Yeah, but your strange theory of electronics has no movement of positive charge carriers anyhow, so what are you on about?
"Negative battery terminal" is stupidly limited when talking about circuits that may have multiple voltages and multiple loops. "Return path" is the simplest way to express the situation.
Oh, and blowhard, do you know what AC stands for? Please, please try to tell me the neutral line in an AC circuit is attached to "the negative supply side!"
By the by, I think I found the problem in the forum software. It doesn't like certain image sites.
You are one of few people I have ever read that I can honestly claim that I have never learned a single thing from. Youre posts can be counted on to be off the top of your head misinterpretations of what you cannot[i/] possible understand, and I have proved it. Until you admit you were wrong about grounding motherboards and your latest dc negative is the return path bullshit, you'll get no meaningful or positive interaction out of me.

Man, IDW, you really to like to show your ignorance, don't you?
From [link to affordablephones.net]
"Simply speaking the telephone ringer this is a device that alerts you to an incoming telephone call. It may be a bell, light, or warbling tone. The telephone company sends a ringing signal which is an AC waveform. Although the common frequency used in the United States is 20 HZ, it can be any frequency between 15 and 68 Hz. Most of the world uses telephone frequencies between 20 and 40 Hz. The voltage at the subscribers end depends upon loop length and number of ringers attached to the telephone line; it could be between 40 and 150 Volts."
"The telephone company may or may not remove the 48 VDC during ringing"
Therefore, in this case, it's pure alternating current. |

If you connect two 8 ohm speakers in parallel to the same audio output terminal rated at 8 ohms, total resistance is decreased radically, and you will fry your finals eventually. It is possible to connect two speakers to the same channel , but they must be in series, in which case impeadance is doubled and the finals are safe. Connecting between channels to create a center channel is safe, so long as impeadance is still withen the range specified, usually 4-8 ohms. |

The outer braided "shield" is not a shield at all, its is a coaxial cable but doesnt have the same function as with rf. It is simply one of two conductors completing the circuit. 50 ohms is the matching impeadance that allows the volume to be set in the middle on the computer to allow an appropriate input level to the auxilary input. Otherwise, without a resistance added the auxillary inputs are overdriven and 1/4 volume on the computer, inviting disaster. |
