rating of transformer at 2 volt amps

Posted by Lewis L on 07/03/2009 16:19

:I bought them as surplus and thought I could use 2 of them (in and out) as transformers for a B suppply someday.
:
::A 2-VA xfmr is pretty small. What's it used for?
::
::But you have to know the rated voltage to compute the rated current.

:::Can someone explain what 2 voltamps translates into as far as amps?


If you are lighting up lightbulbs or heating resistors, two VA is equal to two Watts. But, since you can connect them to things with capacitors and coils which screw up the the VA/Amp relationship all to ****. So to cover their butts, the manufacturers say: "This transformer will put out X Volts (probably on the case) but lets say 6. So at our six Volts output, P=EI, I=P/E, I=2/6, I=.333A

P. S. Hallicrafters is shaping up nicely
