You cannot 'reverse' the polarity of a transformer -it is either wound with 'additive polarity' or 'subtractive polarity', and there's not much you can do about it! For a single transformer, its polarity doesn't really matter. But if you are going to parallel two transformers, then you must know the polarity of each transformer in order to avoid harmful circulating currents in their secondary windings.
-- negative polarity -- positive polarity
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
Polarity
It is not necessary that all salad ingredients must be soluble or miscible; so eat salads without the care of polarity.
Reversing polarity ,changes the rotation of the device you are changing polarity on.
No. Electromagnetic fields have polarity.
From least to most polar: biphenyl >> benzophenone >> benzhydrol
they do not have any electrical property that is polarity sensitive
What can reverse magnetic polarity
Yes integrated circuits have polarity.
