Hi,
I have a 220V to 12V transformer.
It was getting hot and the fired due to a short circuit in its secondary leads.
The first question is why a transformer gets hot while the SECONADRY coli become shorted for a while?
The other question is why the primary coil draws MORE current from the mains when the secondary coil is connected to a load (I.e. why the primary current changes with changes in secondary resistance?)
Thanks
