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.

What does auto in autotransformer stands for?
"Auto" refers to the single winding used an auto transformer.
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
What is the difference between transformers and autotransformers?
A transformer or, more-properly, a mutual transformer, has two windings, the primary and the secondary, which are electrically-isolated from each other, with the secondary voltage induced through mutual induction. An autotransformerconsists of one tapped winding, so the secondary circuit is not electrically isolated from the primary circuit. An autotransformer may be used to either increase or decrease the primary voltage, depending how it is connected.
What is the purpose of auto transformer?
Helps with the starting of large electric motors.AnswerAn autotransformer is a transformer with a single winding, rather than two separate windings. It can be used as a step-up or as a step-down transformer, provided there is no requirement for electrically-isolating the secondary circuit from the primary circuit.
What is the difference between Auto transformer and Power transformer?
An auto transformer has one winding with the output being tapped at some point and therefore has no isolation between primary and secondary. This may make it unsafe or illegal in some applications. A common power transformer has separate windings.
What type of transformer has only a single winding?
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
What does auto in autotransformer stands for?
"Auto" refers to the single winding used an auto transformer.
What type of transformer is used to prevent electrical noise from passing from the primary winding to the secondary winding?
Shielded transformer
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
What is Auto transformer and ordinary transformer?
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy

What are disadvantages autotransformer?
cannot be used as an isolating transformer, because is has common winding.
Which types of windings used in transformer?
Clarify your question. What do you mean by 'type' of winding?
What types names of windings does the transformer have?
The primary winding is connected to the supply. The secondary winding is connected to the load. A tertiary winding (if used) is a third winding, which may be connected in various ways.If the transformer is a three-phase transformer, then there are three common configurations: wye (also known as 'star'), delta (also known as 'mesh'), and zig-zag.
What is the purpose of star delta connection in a transformer?
A star winding has a red yellow and blue phases. The centre point of every stay winding is used as d nuetral point. Hence the star winding in a transformer enables a nuetral point.

It can be used as a step-up or as a step-down transformer, provided there is no requirement for electrically-isolating the secondary circuit from the primary circuit.
What changes a low voltage into a higher voltage?
The step up transformer is used to change the voltage from high to low or low to high voltage by eitherincreasing the number of inding or reducing the number of winding in the transformer,thus when the winding reduced on side of primary winding and ingreasing number of winding on secondary side it means the transformer should be step up transfo0rmer,and when the you increase number of turnsin primary side and reduce turned on secondary sidde the transformer said to be step down transformer
