All batteries have two terminals, one positive and one negative, and usually they need to be hooked up right for the equipment to work. Some equipment will be damaged if you hook the battery up the wrong way - reverse polarity.
Equipment that has reverse polarity protection has something in them which makes them able to stand being hooked up wrong w/o being damaged.
i would never naturally assume any circuitry to be "reverse polarity" by default even if they are. since this can fry a lot of IC, and micro controllers. there are several options to adding a reverse polarity protection circuit to your project you can find three easy to implement circuits here: http://provideyourown.com/2012/reverse-polarity-protection-circuits/
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Reverse the polarity of the magnet.
If, by 'reverse polarity', you mean the accidental reversal of the line and neutral conductors at the socket outlet or receptacle, then the answer is no.
i don't believe you can reverse the polarity on a fuse, they simply regulate the amperage of the circuit they protect,
multiply by -1...
yes
Normal polarity.
we will have straight polarity and reverse polarity,we can produce the weld with good quality
