Reactive power - Reactive Generator research from GotoLuc - discussion thread

[forest]

Again, if you think a little you should realize that only voltage is active component of power, just  consider analogy with water in pipe. If I good remember in physics when we think about power generated (for example mechanical) by energy conversion then something must be dissipated for something to rise. Only voltage in pure Ohmic circuits seems to conform to that....the current is just a bunch of small magnetic particles and we use it to kill the dipole.... Power grid USE reactive power to keep steady voltage on line - that's what I learned from some good presentation , but of course I'm not good in electrical science and sometime must pass for e to comprehend HOW they do that

As far as "splitting the voltage from the current" or however it was put.... this indicates, to me, an incorrect mental model of what "electricity" is. Can you separate the flow of water from its pressure? I don't think so.

Yes you can, a river has flow but no pressure until you dam it in one way or other. Once damed you have pressure but no flow, until you open a hole in the dam.

With the river analogy we're considering the effect of gravity on water, kinetic and head.
Is this comparable with current in a electric circuit?

It is as comparative as using current and voltage to define flow and pressure

I have a question about something that dosnt make sense to me. In Luc's circuit below,why is the voltage being measured on the front side of the cap(across the supply),and the current on the back side of the cap?Should not the voltage and current be measured on the same side of the cap?

Brad,

The probes in that diagram are positioned to measure GRID power.

Granted, I believe some individuals posting here don't realize this.
