p A limits the current which canflow through B and C, and that current which does flowdivides between B and C in proportion to their conductivi-ties. If B has a resistance of 110 ohms and C 220 ohms,then B will carry two parts of the current and, C only one.The combined resistance of all lamps,… … Fig. 650 ance of B and divided by the sum of all the resistances. Ifthe resistance of each of the lamps were 110 ohms, theproblem would work out thus: 110+110X110 iio+iio+iio =731/3 In Fig. 650 the total resistance is 110X220■ 1-110=183 1/3. 110+220 One practical illustration of the above law may…
