I don't think "rated current" is an established technical term and they are using it differently. Though maybe the second unit has electric resistance backup heat?

I don't understand the question.

No, that's just startup current. Look at the power usage and/or EER/COP.

You detect it from in it. So it is reading the field strength at that distance/ location.

I may have interpreted @pines-demon 's question a bit differently; with the sensors that are available, what is worth keeping on and why? Some things - like cameras - would be almost completely useless and high bandwidth, so no point to them. Information about the sun's magnetic field is still...

Mainly they just spread out.

2. Almost everything we use is "electromagnetic radiation" which includes light, IR, UV, radio, gamma, etc. It's all different frequencies of the same stuff. 1. It doesn't lose frequency/wavelength/energy as it travels, it just goes until it hits something and then is either absorbed or...

Is that a crop from a larger picture? What camera settings did you use?

It will probably change the focus - happens with telescopes.

Here's the thing about that: if you fake it well enough it will become true.

Just make sure you frame it as a question and you should be fine. Framing as a statement/argument like "twins paradox proves special relativity is wrong" is how you get in trouble.

There are a lot of things others said that are true/good advice, but it may help to hear from someone with some similar experience, if not quite as severe. It's 25+ years ago, so the details may not be relevant anymore, but the general guidance should be. I got kicked out of the Naval...

Engineers designing buildings must keep the phases as balanced as possible for practical (and maybe code) reasons. But randomness would tend to keep the overall grid pretty well balanced. I'm not sure what, if anything, electricity producers do to actively try to balance the load. There may...

Science yes, inventions no. Science is advancing knowledge, often just for the sake of knowledge. But inventions are typically mothered by necessity. We do have some ability to assemble some things atom by atom, I just don't see why we'd want to apply that to food. Outside of a horribly...

I guess my question is why we'd even want to.
