Figuring wire length with a ohmmeter? | Information by Electrical ...
Apr 29, 2014 · An ordinary ohmmeter won't do it. From the ITT "Radio Engineers Handbook" the resistance of #3 Annealed copper wire at 20 C (68 F) is about 0.197 ohms per 1000n ft. Thus, your resistance for 600 ft would be about 0.118 ohms. To measure this you need a 4 terminal ohmmeter. This you can make by connecting a known DC current of about 10 A thru the ...

Physics. Using an ohmmeter, a student measures the resistance between various points on his body. He finds that the resistance between two points on the same finger is about the same as the resistance between two points on opposite hands—both are several hundred thousand ohms. Furthermore, the resistance decreases when more skin is brought ...

Science. Physics. A common instrument used to measure directly unknown resistance is the ohmmeter. This is actually the simplification of the voltmeter-ammeter method wherein the unknown resistance is computed by simply using Ohm’s Law using the measured voltage and current. Do you think this will give an accurate result? Supposing the ...
