If you are talking about an AC (alternating current) circuit, such as the house mains supply, "reverse polarity" usually means the "hot" and "neutral" wires from the supply have been connected to something the opposite way round to what they should be. If you are talking about a DC (direct current) circuit supplied by a battery, such as in a car, "reverse polarity" usually means the positive and negative leads from the battery have been connected to something the opposite way round to what they should be.

How do you wire for reversed polarity?
the hot and neutral are wired forwards the ground and neutral are wired backwards
What is reverse polarity-?
Reverse polarity is the opposite of normal polarity. Normal polarity in electronics is when you have the positive hooked up to the positive terminal and the negative to the negative terminal. Reverse polarity would be having the positive hooked up to the negative terminal and the negative to the positive terminal. The same concept can be used with magnets.
Does a John Deere B have reverse polarity?
I own a 1948 John Deere B so I know for a fact that B's serial number 201000 and up have positive ground. Don't reverse the polarity cause it'll fry the generator and possibly the starter (the starter might even turn backwards - not sure cause I've always been sure to connect the batter with positive ground). The older B's should most likely be the same as 201000 and up. My dad told me that a lot of old vehicles from the 40's had positive ground. Not sure why though.
When the hot and neutral are wired backward is reversed polarity?
The assumption here is that you're refering to a standard A/C (alternating current) circuit such as those found in the average household or business. In a typical household the power supplied by the power company actually reverses polarity 60 times a second (60 Hz), hence the term alternating current (A/C). In Europe the standard frequency or Hertz (Hz) is 50 at 220 volts. The U.S. standard is, of course, 110 VAC at 60 Hz. So, in answer to your question In most systems you have a 0 volt potential *neutral and a 110 or 220 volt potential *hot, when this gets wired in reverse safety problems can arise, such as a nasty shock when touching grounded equipment.
What can cause nonstart and all electronics to not function on a 1994 Chevy Suburban?
Bad ground, Bad Battery. Or The battery was connected improperly. I.E Reverse Polarity.
Change polarity in single phase 115 volt?
Most technical people believe that AC electricity is not polarized this is an incorrect assumption. Since AC power is just a potential difference between some reference (ground) and a signal it stands to reason reversing the Neutral and the "Hot" should reverse the polarity.
What polarity is used for stick welding?
Reverse. Using a D C machine, electricity travels from the negative post to the positive post. Connecting the electrode holder to the positive post and the ground clamp to the negative post means the current flows from the work to the electrode - reverse polarity. In A C machines it doesn't matter which post the electrode holder is connected to.
What is the use of polarity test?
I will assume that your question is in reference to CT and transformer polarity.In the case of a CT (Current Transformer) they have to be installed in the correct direction for proper metering. The polarity check is used to verify that they are installed correctly and that the polarity marks are correct (if the CT has them).In the case of a transformer there are two types of polarity, additive and subtractive. If you are paralleling transformers you have to ensure that they are the same type polarity in addition to other attributes.Hope this helps.Alternative AnswerIn a new electrical installation, a polarity test is conducted to ensure that socket outlet terminals are correctly wired (line really is line, neutral really is neutral, and the protective conductor (earth/ground) really is protective conductor. It's also important, for example, that the centre pin on an Edison Screw lampholder is connected to line, and not to neutral.
Can you applied the voltage to neutral of the transformer?
The neutral of a transformer is usually grounded. Under this situation, this question is the same as asking whether you can apply a voltage to ground; the answer is yes, but I don't know why you'd want to. Sometimes transformer neutrals are insulated away from ground. If this is done, then you could inject "backwards" from the neutral up into the transformer. Again, I don't know why you would want to do this, though.
Neutral and hot wired backwards?
For a US 3-prong plug, a smaller slot should be hot, the longer slot should be neutral, and the screw that holds the plate on should be ground. Cheap, inexpensive testers are available at hardware stores.
How do you reverse the polarity of a compass that is 180 off?
Well, the easiest way to reverse the polarity of a magnet is to just turn it around. However, inside of every piece of steel, there are magnetized pieces that will make the steel an induced magnet when a magnet is placed on or by the steel. By putting the oppositely polarized magnet on or by the same steel, you may be able to reverse the magnetism of the steel. Or by making it a core of a coil in which direct current flows in such a direction as to re-polarize it
How to tell if a car has reverse polarity door locks?
Hook up a meter to either the lock wire or unlock wire, press the lock button and the the unlock button. you will see the meter go to 12v on 1 press and open circuit on the other. if its just 12v and ground, then its positive polarity door locks.
