OK ...
All i am doing is spinning a magnet inside a coil of magnet wire.
The coil goes to a rectifier.
My resistor is across the rectifier output.
When i use a 1K resistor the magnet stops spinning.
When i use a 10k resistor the magnet slows down but continues to spin at a lower speed.
I thought that more resistance (10k as a pose to 1k) would be more of a load but 1k stops the magnet and 10k doesn't ?
What am i not understanding please ?
Gary,
It is the opposite. Low Ohm is higher load.
Alex.
Groundloop thankyou !
I think far too literally. I assumed more ohms is more resistance ?
It seems counter-intuitive to me.
Gary,
More Ohms is more resistance. With more resistance the current goes down,
thus LESS load to you circuit.
Alex.
Thankyou for clearing that up, i have a block with maths but i understand now.
Reading the formulae in conjunction with your explanation made me see it.
Thanks again Alex :)

@Groundloop!
Thats the first time Ive ever seen a U for Voltage. Where does that designation come from?
First time i'd seen it to but it also occurs on this page if you search the page (CTRL-F) for 'uout' :

@IotaYodi,
The standard metric unit of electric potential difference is Volt, abbreviated V and
named in honor of Alessandra Volta.

That I knew. What your saying then the U is actually a V.
Must be a typo on the Image.
@IotaYodi,
There is a difference in European and US standard of the letter used for Volt.
In US it is V. We use U for volt. For me the drawing is correct. You just
change the letter U to a V and the drawing will be correct for you. We use Ub
for battery voltage, Ui for input voltage, Uo for output voltage. You can use Vb,
Vi and Vo if you like. See: http://www.sengpielaudio.com/Rechner-ohmschesgesetz.htm
If you click the English version: http://www.sengpielaudio.com/calculator-ohmslaw.htm
then the use is V.

Aha! Learn something new everyday. Thanks Groundloop!
