If one had a microwave oven transformer (MOT) from a microwave that was said to be 1200W, and the transformer itself had an output of 2300V, would that mean that the current would be: Power = Current * Voltage 1200W = Current * 2300V Current = 0.52A The reason I ask is because: I'm looking to power said MOT by a Variac that is said to be 0-140VAC at 6A. I'm trying to verify that I won't overload the current of the Variac with said MOT. Also, I'm going to rectify the output of the MOT with a diode bridge consisting of four diodes said to be 9kV and 500mA. I understand that at 9kV and 0.5A, the power would be 4.5kW -- way higher that the output of the MOT. But, does the maximum current of the diodes increase as the voltage decreases? In other words, even though they say 500mA, could they sustain higher current at lower voltages, such as 500V? I'm sure to many of you these are laughable questions. :shy: Any help, though, would be much appreciated! Thanks in advance.
