If a machine is never 100% efficient transforming energy into work because part of the energy is converted into heat, does it mean an electric heater is 100% efficient? @showerthoughts@lemmy.world

Not quite. Some is lost in magnetic flux and mechanical deformation. But that is a VERY small about.

Do those not end up as heat later down the line as well?

[-] Ross_audio@lemmy.world 27 points 8 months ago

Yes, but magnetic flux causes radio waves and there isn't a guarantee these will turn into heat in the space you are heating.

That's an interesting point about radio emissions leaving the heated space.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct
