Repeat the good answers already given: too small to matter.

We are talking about 64 milliamperes of reactive current with a 5-Henry choke used on a 120 volt, 60 Hz circuit. This is 7.7 reactive volt-amps representing about as much current as a night light.

Considering the total number of audiophiles around, and the fraction of those motivated to use such tweaks, the burden of this reactive current on the power grid is negligible.

Now, think about the 5 watts of real power dissipated by your door bell transformer 24/7. Everyone has one of these, along with wall-wart supplies for many other appliances that waste energy due to similar inefficiencies. These losses require generation capacity, and are a real problem for the grid.

My understanding is that reactive power does not show up on OUR bills - Christopher Witmer 07:25:14 04/27/07 (3)
