Why do the transformers on rechargable domestic appliances have a 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 transformer to a product instead of the 200mA supplied with the product? I would expect the current flowing to be the same – or have I got it all wrong???

Thanks ROMOS Karma - I have read the link and I understand the transformer theory but it still does not answer my specific question.I would be grateful for a detailed explanation
