    Why do transformers on re-chargable domestic appliances have a specific current rating?

    I cannot understand why the transformers on rechargeable domestic appliances are given a current rating eg 200mA, 300mA, 500mA, etc. Surely, provided that the voltage is correct, under Ohm’s Law the current flowing will be determined by the voltage and resistance of the actual circuit. What would be the result of plugging in, say, a 500mA rated  transformer to a product instead of the 200mA supplied with that product? I would expect the current flowing to be the same – or have I got it all wrong??? I do understand transformer theory but would like a positive answer to this specific question please

    Sorry wonderdyke Karma but this does not answer my question - can you please be specific instead of referring to other sites. This is the second time that I have asked this question and the second time I have been referred to an irrelevant explanation on another site.
