A controller has a large amount of capacitors that have to be filled (precharged) whenever you turn on a controller, and in doing so there will be a very large surge of electricity. Such a surge can do damage to components, so you put a resistor in line to slow that surge down to a save level, and once ... Web6 years ago. Here's one path to an answer. I'll start with the basic capacitor equation: q = Cv. (q = charge, C = capacitance, v = voltage) Now convert the variables to unit names. The units of q are Coul (Coulombs), units of capacitance are F (farads), v stays volts. Substitute in the unit names and you get the definition of a farad, F = Coul/V.
