Hello there,
I am wondering why the resistor maximum voltage is not simply the square root of the product of its wattage and its resistance. According to the attached datasheet (pdf) for example, the maximum voltage of a 2.2 mega ohm, 0.25W resistor, is 250V (instead of 742V as calculated). Other datasheets show similar disparity. Could anyone explain what's going on?
Thanks
ed.
