Ohm's law, in action!

I think this 100% goes for rock crawlers 100% because we are trying to be the most efficient we're trying to turn that motor at the slowest Revolution possible like all the power we can get the better

[@Crawlingrc3903]

Cool thanks this was very informative. I have learned so much about motors n esc from watchimg your videos i am grateful that you do this

[@brianbrigg57]

Cool stuff and helpful. The really neat thing is that this way of measurement takes the resistance of the leads from the power supply and meter out of the equation. If you want the ultimate in low ohm measurement precision you can use the Kelvin double bridge method which gets down to 0.0001 ohms but it's more fiddly and unnecessary for the use cases that we mostly need. One little thing is that the symbol for an inductor was used in place of the resistor symbol in the drawing. The resistor symbol is the sawtooth zigzag one.

@brianbrigg57 oh yes, that is an inductor symbol! At least I'm measuring a very inductive object, lol!

Good evening, is it also better to have a lower number awg wire for wire leads to your esc when racing is there a optimum. Thanks in advance

[@stingerrc]

Always top

This is all so very interesting I would definitely like to see the battery thing but I damn sure want you to be safe

[@JKSJ683]

Would a battery charger work for the CCCV supply?

[@HolmesHobbies]

@@JKSJ683 if it has hot wire mode, yes

[@Paul__FC]

Ohhh.... listening very close.

Leave poor Kelvin alone already!!
