12-0-12 500mA transformer enquiry

[vis5254]

This might be the silliest thing asked ever , but i just have a lack of clarity . ie , I've 12-0-12 500mA step down transformer.  if I provide 12v ac voltage parallel to 10 ohm resistor , theoretically ohms suggest i would get 12/10 = 1.2A .. Do I ??  practically ??will my transformer current rating might affect this situation ?

I was planning to generate 1 or 2 A ac current for current sensor testing !

You would be overloading the transformer.  It can deliver 12 Volts at a half ampere; any more load will take it beyond its ratings.  You need a bigger one.

You will get 12Vrms with 24ohm resistor wired to 12V--0 terminals.
You will get 24Vrms with 48ohm resistor wired to 12V--12V terminals.
