Only if the resistive heater in question is DC or AC with reactive power compensation
- ruperthair 2mo agoA purely resistive heater, by definition, has no reactive component so there's no reactive power considerer. The 0.1% mentioned might be the light that the project produces.
- choo-t 2mo agoAssuming you're not in an endless vacuum, the light will also become heat.
- stymaar 2mo agoI think it's fair to separate it from the direct heat generation because if you look at second order effects like that, pretty much all of the energy ends up being radiated away as infrared in space.
- wat10000 2mo agoIt's hardly a second order effect if you're talking about heating a space and the light is absorbed by the walls of that space.
- smrq 2mo agoIt's quite literally a second order effect. The first order effect is light generation, and a consequence of that effect is heat generation via light absorption.
- wat10000 2mo agoDepends on where you want to draw the lines. Heating the room and emitting light could both be a second-order effect if you want to say that the first order is heating up the actual heater.
- ruperthair 2mo agoNice point! Would it be the same for sound that doesn't escape a room?
