I think i understand now. It's the readings taken on the components or the load it's taking or the circuit that feeds it. Not what someone has added later. Am i getting there. Reason for confusion the smallest resistor i could get in alloy case is 25 watts. I thought this would throw all calcs out. What i did was place a sheet of alloy on top of the ceramic resistor. 50 x 50 x 8mm no paste. I may be imagining things but the plate wasn't even warm. I could even keep my hand on the resistor. It had been on for 2 hours or so. If this is ok. I will solder resistor other side of board it will then protude through the top of alloy case after cutting a hole. I will then fasten plate to resistor using contact paste. What do you's reckon.
