This generates a phase shift so that the voltage and current vectors are no longer at 90 degrees. This causes a power loss. It is also pushed back towards the generator and can damage plant and equipment.
From the consumers POV it means that more power is being consumed to get the same amount of work done. When the voltage and current are completely out of phase no useful work is being done even though the power is being transmitted.
More current, no more power. When the phase shift is 90° the power is zero.
Right. And it really buqqers up the generator and other equipment!
there are refrigerator mechanism that don't use electric motors; Einstein invented one. But they aren't very popular.
Because they are very inefficient and expensive.
There are many who contest that. At the time, material technology and manufacturing technique was limiting. Revising that today can make it much more reliable and much more efficient. More to the point, it doesn't need electricity. Any heat source will do. https://www.theguardian.com/science/2008/sep/21/scienceofclimatechange.clima... There's a point where the notional 'efficiency' really doesn't matter. https://www.scientificamerican.com/article/solar-refrigeration/ I bet those fishermen in the village of Maruata don't worry about 'efficiency' of their ice makers. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
