I've got a bunch of mains transformers lying around that give out 12V AC which is perfect for all my electronics projects.
How do I determine the VA of the transformer if it has no markings on it. I don't want to start using it and then have it melt down on me as I'm drawing too much current from it.
Would I need to put a load on it and then if it gets warm I'm overloading it? Sounds dodgy - there must be another way?
