hi all, we are doing a college project and need to design a step down transformer CAD only. what has me stumped is that we need to include the minimum resistance needed for the primary to be used on single phase 240ac.
can anyone help? if you can include the actual equation it would be a tremendous help. I remember that there is such a spec from the dim and distant past, but Google turns up nothing :-(
also because its design only and we don't need to build it, I need the figures as they would be in a "perfect world" in other words I don't need to take into account what adjustments I would need for the real world, I need the textbook calculations.
many thanks to anyone who helps.
