What happens if you connect a positive wire to a negative wire?
If you connect positive to negative directly with a wire, you get a very low resistance circuit.
The lower the resistance, the higher the current.
The is called a short circuit.
Batteries have internal resistance, so this has to be added to the resistance of the wire..
What color wires are positive and negative?
In DC circuits, the positive pole is usually marked red (or “+”) and the negative pole is usually marked black (or “−”), but other color schemes are sometimes used in automotive and telecommunications systems. On a car battery, the positive pole usually has a larger diameter than the negative pole.
Is there a positive and negative on low voltage wire?
Low voltage wire does not have polarity, it does not matter which of the two wire connects to the Common Terminal and which to the Voltage Terminal, as long as one wire goes to each. … It is easier to see and insert the wires into their terminals when the transformer is lying on the ground.
Is white positive or negative?
In an AC circuit, the convention in the US is that black and red are “hot” (alternates between positive and negative,) and white is “neutral” or “zero” (with a close-to-zero potential difference to earth/ground) and greeen or green-and-yellow is “protective earth.” If you have a three-phase system, the third hot phase …
Is red wire live or neutral?

How do you know which speaker wire is positive and negative?
Every speaker wire will have an indicator to tell them apart, such as color. In some high-end speaker wires, the insulation is transparent, or see-through, enough to see the bare wires. When this is the case, usually the silver wire will be the positive polarity and the copper wire will be negative.
How can you tell if I reversed my positive and negative on my speakers?
When the positive amplifier terminal is connected to the positive speaker terminal and the negative amplifier terminal is connected to the negative speaker terminal, the speaker will be in correct polarity. When these connections are swapped, the speaker will be in reverse polarity.
What happens when you mix up positive and negative?
In extreme cases, the battery can crack, ignite, then explode. On the other hand, your vehicles components should be protected thanks to the fuse. If you accidentally connect the negative clamp to the positive pole, the fuse should take the brunt of the power surge and burnout.
What happens when polarity is reversed on speaker?
Bass response always suffers when polarity is reversed. Bass tones are generated in part by the pressurization of the air in the space surrounding the speaker. When the signal is out of phase, the bass speaker moves in when it should move out.
Is a yellow wire positive or negative?
In DC circuits, the Positive is any color(generally red) and negative is black. Hence a yellow wire may be Positive if the other wire is black(negative).
What color is positive wire?
redPositive – The wire for the positive current is red. Negative – The wire for the negative current is black. Ground – The ground wire (if present) will be white or grey.
Is solid color wire positive?
2 Answers. The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. for the “wall wart” power supplies. Usually* the wire with the white stripe or the dashed lines carries the “positive” (+) end, while the other, unmarked wire carries the “negative” (-) end.
