Inside a "Home Electric Power KWH Meter" - US

Hi Fuzzy
I confirm to you as far as possible.
But the last statement is false (in case of no misunderstanding)

As example we take a ordanary bulb in focus.
The resistor (filament) in a working condition does not change its value.
100W = P=U*I   I=P/U 100/110 =  0,909A  R=U/I = 121,01Ohm          US Voltage
100W = 100/240 = 0,416A   240/0,416 = 576,92 Ohm                       EU  Voltage

If you put a 100 W  Eu Bulb on a  US Grid  I = U/R than the Bulb will take 1,983A  and the filament will melt in a second.
What i want to tell you is, that on a ordenary resistor, there is no circuit, that corrects ( adjust) the resistor. As heaters , Bulbs and transformers.

Hi helmut,

I think were saying the same thing kinda ..... 

Given Knowns -

P = power (watts)
V = voltage
I = amps
R = resistance (ohms)

electrical object (1) one 100 watt lamp (resistive load) 220 volt ( no 220-240 volt incandescent lamps in USA "only" 120 volt )
----------------------------------------------------------------------------------------------------
P '/. V = I

100watts '/, 220volts = .45 amps
100watts '/, 230volts = .43 amps
100watts '/, 240volts = .42 amps
100watts '/, 250volts = .40 amps

Voltage increases Amperage goes down
----------------------------------------------------------------------------------------------------

V '/. I = R

220volts '/, .45amps = 488.88 ohms (R)
230volts '/, .43amps = 534.88 ohms
240volts '/, .42amps = 571.42 ohms
250volts '/, .40amps = 625.00 ohms

Voltage increases Resistance increases
----------------------------------------------------------------------------------------------------

You are correct if a EU 100 watt incandescent lamp was used in a US 240 volt circuit it would work but have a short life span because of the  large voltage fluctuations

---------------------------------------------------------------------------------------------------

100watt '/, 120volt = .83 amps

120volts '/, .83amps = 144.58 ohms (R)

Using a EU 100 watt incandescent lamp on a US 120 volt circuit ...... wouldn't the lamp filament burn really "dim" and not burn out the lamp filament

Fuzzy:

Thank you for your sacrifice for the sake of science.  I have always wondered what was inside one of these.  I did try a test of advice I read on the net and, for some reason, it appeared to actually work.  I held 2 strong neos alongside my meter lined up at the sides left and right at the largest circumference of the glass.  The meter slowed to about half the speed it was going.  I removed the magnets and it sped back up.  I have no idea what this worked this way, and I have no intention of stealing power (and I suggest no one else do it either) but have you ever heard of this?

I will cut my power expenses using earth batteries, joule thief circuits and Bedini motors.  I was just curious to see if you might know why this works?  PS these were very strong neos.  So strong, they stuck to the glass being attracted to something inside and I didn't even have to hold them.

Hi Fuzzy

Your calculation shows the conditions.
If one will save Money on the electric bill, one has to keep the Voltage down.
But halogen bulbs need standard voltage.

I held 2 strong neos alongside my meter lined up at the sides left and right at the largest circumference of the glass.  The meter slowed to about half the speed it was going.  I removed the magnets and it sped back up. 

The meter slowed because the added magnets created eddy currents in the moving aluminum disc. This created a braking action. The same is done with the magnet already in the meter. Without this existing magnet the disc would rotate at incredible speeds and not stop when you stopped using power.

Note how the 'current' loops pass through their core in different directions. If they didn't the fields they created would cancel and the disk would not move. As it is, they sum the current fields.

These old meters are a good example of how rotation can be done. The voltage and current fields are at 90 degrees to each other. This creates the third vector 'rotation' of the aluminum disc.
