Reverse polarity means that the direction of an energy flow is opposite of normal. In house wiring, it would mean that the hot wire (in the US, the black wire) was crossed with theneutral wire (in the US, white wire). Appliances would still function, but the flow of current is reversed (and unsafe)
False
A reverse fault is formed here
we do not know the cause
Reverse failts are caused by compression. Normal faults however are formed by tension.
Take it out of reverse.
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
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/
no
nothing
it really doesnt
