The absolute simplest transformer would be two pieces of wire laid next to each other. Changing current in one wire would induce a magnetic field that in turn induced a current in the other wire. This would not be efficient though. Coiling the wires concentrically would increase their interaction and efficiency, but for a functional, simple transformer, wrapping the wires around a soft ferromagnetic materiel with a high magnetic permeability and high field saturation makes for a much more efficient transformer.

Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
actualy it is, the japinese made a real transformer.

There are normally only one set of primary windings in a transformer. Some may have multiple windings though so that they can cover a wider range of input voltages.

The price of remote control Transformer varies; it can start at $30 for a simple version to up for $300 for a more advanced version.
The transformer ducts are usually made up of strips of transformer board that is glued to the Diamond patter resin coated paper. It is widely used by transformers for manufacturing oil immersed distribution transformer windings.

A transformer's 'nameplate' lists all the data necessary to identify the rating, connections, etc., of a transformer. Part of this data is the 'vector group' information which applies to three-phase transformers, and which, in simple terms, tells us whether or not the transformer can be connected in parallel with another.
Any thing that reduces human effort is simple machine whether it is a simple pulley or a complex machine. e.g. axel,gears,transformer,lathe etc,
AC or DC? AC - use a transformer, DC - forget it - not simple or cheap.
