What is the main difference between small transformers 50W and larger tranformers and what key specifications will normally decide the price for a tranformer.?

Answer

There is no fundamental difference. The principal of the tarnsformer is always the same. It uses the principal that a magnetic feild can be formed by a coil. Like whise a changing magnetic field will generate a voltage in an electrical coil. The power of a transformer is defined by how much current the coil wires can carry. The thicker the wires the more current, and the lower the internal resistance. also the core of the transformer can be magnetically saturated which in return limits the power that can be transformed. The price of a tranformer is made up of labour, materials, interlectual propperty and depends on the location where it is made. In other words a large audio transformer made in the USA will be much more expensive than a small power supply transformer made in China
