Hi , It works on the principle that mutual induction between two coils.

How can you determine the polarity of the leads of a transformer rectifier so you can connect a suitable plug?
rectifiers have two terminals.it has a circular ring printed on its body.this terminal is negative or n type.but when you connect any terminal of a rectifier to any of the leads of transformer it works reverse.e.g if u connect -ve terminal to the transformer it will give +ve potential,so the other terminal of transformer without rectifier will give -ve potential.
Why a two winding transformer is used instead of single winding transformer?
You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.

Did McDonalds ever give out transformer toys in its Happy Meals?
Yes they did in fact give out Transformer toys on at least two occasion. One time for the original TV show, and another time for one of the movies.
Should you explain if the question says 'give two reasons why'?
If a question states "Give two reasons why." then yes, generally you will need to explain your reasoning.
Conversion of 2-winding transformer into auto transformer?
Yes, you can use a mutual (2-winding) transformer as an autotransformer, by connecting the two windings in series. For example, if you have a 240:120 V transformer, connecting the two windings in series and supplying the 240-V winding with 240 V can give you a secondary voltage of 360 V. But you must take into account the polarity of the transformer, and realise its capacity will change.
Why is it the oil transformer commonly install outdoor?
Most outdoor power and distribution transformers are oil filled. There are two reasons for this: (1) to cool the transformer and, (2) insulate the windings and other components, allowing the overall physical size of the transformer to be reduced and, therefore, provide a smaller 'footprint'.

Why would you use a three phase transformer in place of a single phase transformer?
the necesscity of two three phase transformers operating in parallel are as follows...if the one transformer fails to give supply,then another transformer can be used in parallel and hance,continuity of supply can be maintained.one transformer can be easily take out from the supply for repair & maintanance.if the load on the substation increases beyond the rated values of transformer, then another transformer can be used to share rhe load of the substation.
