...equal to that of 3 5 miles of wire. Resistance.— The resistance of a conductor (of uniform section) is directly proportional to its length and inversely proportional to the area of its cross-section. If /j and /„ are the lengths of two uniform conductors made of the same material,...

...that of 1ft. of copper wire Imil. in diam. at 15 5" centigrade, which = 10'323 ohms, then the size of any conductor is directly proportional to its length, and inversely proportional to its area, so that for the 100 yards of No. 20 BWG proceed as follows : 10-323 x 300 = resistance of...

...section from the values given in the table are exceedingly simple. Both experiment and theory show that the resistance of any conductor is directly proportional to its length and inversely proportional to its sectional area. Put into symbols this rule may be written — where / is the length, A the area...

...distance from the dynamo to the end of the line. It has already been shown that the resistance of a wire is directly proportional to its length and inversely proportional to the area of its cross-section, and we may then say that R-KX_L A ' when A" is a constant that depends on the units...

...distance from the dynamo to the end of the line. It has already been shown that the resistance of a wire is directly proportional to its length and inversely proportional to the area of its cross-section, and we may then say that Kx L -^T-> when K is a constant that depends on the units used...

...have seen, that Hence K = p-. a 141. Specific Resistance1. Thus the resistance of a uniform wire is proportional to its length and inversely proportional to the area of its cross section. The quantity p is the resistance of a piece of the wire 1 cm. in length, having an area of 1 sq. cm....

...cross section is equal to one square millimeter. The resistance of a conductor of any given material is directly proportional to its length and inversely proportional to the area of its cross section. 474 ELECTROLYTIC DETERMINATION OF METALS 475 The specific resistance of a substance is the resistance...

...distance from the dynamo to the end of the line. It has already been shown that the resistance of a wire is directly proportional to its length and inversely proportional to the area of its KL cross-section, or R = -- , where K is a constant that depends fi on the units used for expressing...

...the resistance and length of another conductor of the same kind. II. The resistance of a conductor is inversely proportional to the area of its cross section, or to the square of its diameter if it is round ; that is, r : r' = d'z : d?, r being the resistance of a wire whose diameter is d,...
