Homework Statement
Why does the voltage regulation of a transformer become negative when a capacitive load is attached? It causes the voltage across the secondary winding to increases rather than decrease, as would be the case for a resistive load. But why?

Hi. Why does one conduct an open-circuit and a short-circuit test on a transformer to determine its equivalent circuit parameters? I've read that a) the open-circuit test determines the parallel parameters - the R and X equating to the core loss, and b) the short-circuit...
