and where's the energy [volts or current or especially watts] that is lost to heat at the resistor? doesn't Kirchoffs equality see the
heat lost as current out? kinda like the pinhole in the hose where the water out the business end = the water in less the loss from the pin hole - like the canvas hoses fire depts usta use, weeping alla way along
I was always a bit iffy on them lil electrons leapin from hole to hole til they fell into the 'earth', but it seems some of'em must commit hari-kari when they hit the resistor
I'm not sure I understand the theories of hydraulics either, but my hydraulic pressing equipt has been working reliably since I put it together 20+ years ago, and tho there's slight weeping around the rams, I haven't added anything to the reservoir in that time!
and ol_blue, I can testify that a 2 & 3 horse motors do convert quite a few of my dollars to heat - doesn't the back emf have more to do w/ the generator thing and the variability of the resistance of the running motor - folks are always asking why I leave'em runnin idle
question is, considering that the electrical circuit is really a closed one, ground being the completion of the loop, and the tires insulating the whole thing from the earth, the fact that batteries run outta amps pretty fast indicates the 'equality' is a one way street - the amps are going someplace other than "back to minus", and the motor requires very little to keep it turnin once started, so the actual energy must nearly all be going into heat, one place or other - the outlet of the 'hose' isn't going back into the reservoir like my hydraulic pumps
