Basic transistors have three lead contacts that do have polarity . There are two kinds referred to as P-N-P (for positive-negative-positive leads) and N-P-N (for negative-positive-negative leads).
-- negative polarity -- positive polarity
Reversing polarity ,changes the rotation of the device you are changing polarity on.
No. Electromagnetic fields have polarity.
a speaker polarity is sub mainframe of the ................................
Yes integrated circuits have polarity.
they do not have any electrical property that is polarity sensitive
Its polarity is zero.CCl4 is non polar
the polarity of the battery is reversed
The polarity of both ends of a magnet is different. The positive and negative polarity exist for a magnet.
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.
Yes!
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.
