An illustration from The principles of physics, 1895, leaf 538
is due to a determinable E.M.F.in the circuit, and fractional parts of the circuit require fractionalparts of the total E.M.F. The portion of the total E.M.F. exertedin forcing the current through any section of the circuit is in exactproportion to the relative resistance of such section. For… … Fig. 399. 618 ETHEE DYNAMICS. If the same battery supply a line of 1000 rniits resistance, theenergy expended in the outer oil-cuit is about j^j of the totalenergy. The electrical efficiency of an electric generator is theresistance of the outer circuit divided by the total resistance. Inthe…
