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.
What else can I help you with?
Why the polarity of transformer is important?
a polarity test is a test which use to check the polarity of tranformer.the rision of this test to running the two or more transformer in parallel.like bettry situation or to fin the terminals
What will happen if the transformers working in parallel are not connected with regard to polarity?
when two transformer are connected in parallel condition,and the polarity of transformer are opposite to each other then a large circulating current flow through out the winding,therefore a very small current flow thro, the load .therefore lifespan of transformer will be reduced.
A reversed polarity is when the hot and neutral are wired backwards?
Yes in AC circuits the terminology reversed polarity means the hot and neutral are reversed to what they should be. In DC circuits reversed polarity means that the positive and negative terminals are reversed to what they should be.
Can you get -5Volts as output when polarity is reversed?
yes.you can get 5v output even when the polarity is reversed. In a 5v battery, if u reverse the polarity, then u'll get the same 5v as output , but in the opposite direction.(i.e.,)-5v(negative 5 volt
Is polarity important with fluorescent under cabinet lights?
Yes, polarity is always important. Many under cabinet fluorescent fixtures are small enough to use a small transformer rather than a ballast. But even then, the transformer will have a longer life if it's wired with correct polarity.
Can you use the word polarity in a sentence?
the polarity of the battery is reversed

What is the word for particles with reversed magnetic polarity?
a

What are particles with reversed magnetic polarity called?
Antimatter
What is the aim of doing polarity test on the transformer?
Knowing the polarity of transformers is important if they are to be connected in parallel.

What happen if all the diode in bridge rectifier is reversed?
it will work as a rectifier . because the AC current to be rectified will not be effected by this change. the out put DC polarity will be changed.
Why is the polarity of the output and input is same in ac transformer?
polarity play essential role in protection purpose if you have done wrong polarity in yours system then protection will operate under normal operationFurther AnswerThe polarity of a single-phase transformer describes the phase relationship of the secondary voltage relative to the primary voltage. Polarity is described as being either 'additive' or 'subtractive'. Knowing a transformer's polarity is one of the essential requirements for paralleling a pair of individual transformers.
What is the name for particles with reversed magnetic polarity?
Particles with reversed magnetic polarity are known as antiparticles. These antiparticles have the opposite charge of their corresponding particles and their behavior is governed by the same physical laws.
When the Earth's polarity is reversed is the Coriolis effect also reversed?
No. The reversal of polarity is a reversal of Earth's magnetic poles. The Corilolis effect is a direct consequence of Earth's rotation and is not affected by the magnetic field.
