om general considerations relating to electric energy,and have expressed above in three different but equivalent formulae,was discovered experimentally by Joule about 1843, at a timewhen the true nature of electromotive force was very impeifectlyrecognised. It is consequently known as Joules law.… … and the ratio mk : mo the strength of the current. Then if wedraw KP at right angles to KO, the length, MP, represents the energyexpended in the circuit per second,—that is to say, the energy con-verted into heat per second in the whole circuit. To get the heatgenerated in the external conductor…
