WebSep 13, 2024 · Take a look at the wiring diagram. The ohms for that wire is specified on the diagram. I think it is about 2 ohms. Check your ohm meter to see if it can accurately show a 2 ohm resistance. I screwed up a job once because my meter was not capable of reading very low resistances. WebThe length is 12 meters. Notice, we're asking, what's the resistance of the wire itself? Now there's not really a quote-unquote resistor in here. But every piece of wire's gonna offer some resistance. And this formula applies just as well to a piece of wire as it does to a resistor. So, the length of the wire's 12 meters, and the diameter is 0.01.
