The cable source adds point one five ohms of wire resistance to contact resistance. Its dusty contact branch uses point one eight ohms, making total resistance point three three. Joule loss is current squared times that total. At two amperes it gives one point three two watts; at four amperes it gives five point two eight watts, four times as much. Both bars show watts on one one-hundred-twenty-pixel scale. These coefficients are source assumptions, not measurements of a particular cable or an electrical safety rating. At four amperes the dusty contact branch gives five point two eight watts. Switching dust off uses point zero two ohms of contact resistance plus point one five wire resistance, giving two point seven two watts. Both bars share the same watt scale. The geometry-dependent coiling term changes the separate temperature and inductance proxies, while this resistance branch determines the current-squared Joule term. The hidden original dust checkbox and all native presets remain unchanged. The source entropy-generation proxy divides power loss by ambient temperature in kelvin, then multiplies by one thousand to display milliwatts per kelvin. At its fixed twenty-five degrees Celsius ambient, the denominator is two hundred ninety-eight point one five kelvin. Loss five point two eight watts gives about seventeen point seven one milliwatts per kelvin; loss two point seven two gives about nine point one two. Both bars measure the same unit. The drawn heatmap and geometric inductance are authored approximations; this export does not validate a real thermal or electromagnetic cable solver.
