I always hesitate when dimensioning a transformer for a DC power supply, and I guess I sometimes overdimension them. My confusion stems from the difference in transformer and DC voltage.
If I need 10V DC @ 1A, will a 10VA transformer do? My gut feeling says I need more, so I use a bigger transformer, but how much bigger does it have to be?
