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.
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. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
