In measuring the length and heigth of a part, I came up with LxH=11.86 (this is the total of the part) I divided 32 into this number to come up with 0.371amps. On the power supply calculater, I typed in 11.86 as my calculation and it said invalid, but gave me a number of .83amps. I cooked my part. Could someone please tell me if I am right by dividing my answer of my part into 32 to always get the amp total? And also why is it everytime I type a number into the power supply calculater it always says invalid, but gives me an amp total to use. Thanks, Jamie
