Is Live Wire positive or negative?
On a car battery, the positive pole usually has a larger diameter than the negative pole.
Modern cars have the negative terminal of the battery connected to the vehicle’s body, and the positive terminal provides the live wire to the various systems..
Do you WIRE positive to negative?
You have to remember to use the same side of the wire on the same sides of the terminals. Hence positive terminal with lined wire to positive terminal, and Negative terminal to wire without line on it to negative terminal.
Is yellow wire positive or negative?
Is yellow wire negative or positive? 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 happens if positive and negative wires touch?
Since these wires have a difference in electrical potential (voltage) current will flow and you’ll get a spark. It’s a process: The physical contact between the wires gets broken. The air ionizes, which means that the atoms in the air around the now-broken connection start to carry current.
What does a negative wire do?
Negatively charged electrons wish to travel to the positive portion of the battery — and if they have to rev up your personal electric shaver along the way to get there, they’ll do it. … The source of electricity must have two terminals: a positive terminal and a negative terminal.
What is positive and negative in electrical wires?
Positive – 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.
What happens if you mix up positive and negative speaker wires?
Reversing polarity with multiple speakers can cause more noticeable effects. If both speakers are wired the same, whether in the correct polarity or reversed polarity, there will be virtually no effect.
Do I connect positive or negative first?
When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.” When you are replacing your car battery, It isn’t always easy to remember the order in which to disconnect and reconnect the terminals.
What happens when you connect positive to negative?
When the battery cables are hooked up with the negative to the positive and positive to the negative terminals, the battery can explode. This is true for the battery being charged and the battery in another car being used to supply the charge.
What happens if you wire live and neutral wrong?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair.
