the other outside, and the same quantity ofelectricity is discharged through the circuit. Experiment showsthat the quantity of heat liberated, and consequently also the re-sistance, is, for a given metal, directly proportional to the lengthof the wire, and inversely proportional to its area of… … Fig. 75. of a metal—that is to say, the resistance expressed in any unitswhich it offers for unit length and unit section—the resistance, R,of a conductor of this metal, of length I, and section s, in termsof the same unit, will be 11 = p — s We shall hereafter become acquainted with methods more…
