Operating a transformer at half the voltage? Answered
What could be the effects of the output when operating a transformer at half its rated voltage, specifically to the amperage?
as two examples:
If I had a transformer rated for an input of 240v and an output of 20A at 24v and I was to supply the primary with 120v, what would happen to the output?
If I had a variac (autotransformer, variable transformer, ect.) and it was rated for an input of 240v with an output of 0-260v at 11A, what would happen to the output ratings at only 120v?
