ter almost the whole of the heat produced by the discharge.Thus with an apparatus called the universal discharger (Fig. 76),we may raise the temperature of a fine wire of any materialstretched between the two knobs B and d sufficiently to melt it,or even to volatilise it. 91] HEATING EFFECTS 139 If… … if we disregard any losses by radiation. Hence, for a given metal, the temperature depends only on themass of metal; it is higher as the mass is less—that is to say, asthe wire is finer and shorter.For two wires of the samemass but of different metals,it is inversely as the specificheat; lastly,…
