This is probably going to seem like a dumb question to most of you. But I can't seem to find a answer.

If you have a transformer with the following specs:
Primary- 240VAC, Secondary- 120VAC, VA- 500. Now what would the values be if the Primary was connected to 120VAC ?

I know that the Secondary voltage should be 60VAC but what happens to the VA rating?

Thank you, Cary

Thank you for replying.

In my first example - 500VA / 120V = 4.16 Amps

In the second- 250VA / 60V = 4.16Amps

Is this correct? The available amps stays the same? Even though the VA is halved?

Or am I thinking wrong that VA is figured the same as Watts?
