Talk:Voltage Drop

From an email on the DCC 4 Everyone mailing list:

It should be noted that the resistance of Nickel Silver, also known as German silver and containing no silver at all, is more than nineteen times that of annealed copper. German silver has a resistance of 33x10^-6 ohm cm. Annealed copper has a resistance of 1.724x10^-6 ohm cm. German silver resistance is 33/1.724=19.14 times that of annealed copper.

>From data posted by Doc Denny;

Atlas/Shinohara Code 100 is 0.038 ohm per foot, approximately the same as AWG 26 SOLID wire at 0.0408 ohm per foot.

Walthers (Shinohara) Code 83 is 0.052 ohm per foot, approximately the same as AWG 27 SOLID wire at 0.0515 ohm per foot.

Atlas/Micro Engineering Code 83 is 0.078 ohm per foot, approximately the same as AWG 28 SOLID wire at 0.0649 ohm per foot.

Shinohara Code 70 is 0.077 ohm per foot, also approximately the same as AWG 28 SOLID wire at 0.0649 ohm per foot.

Micro Engineering Code 70 is 0.116 ohm per foot, approximately the same as AWG 30 SOLID wire at 0.103 ohm per foot.

If the 12AWG copper wire in your house was replaced with Nickel Silver with the same resistance, the conductor would be approximately 3/8 inch (10mm) in diameter.
