e not connected in series with the fixed coils. If thepower absorbed in say a lamp L is required, the current in the lamp iscaused to How through the fixed coils A, B, C, and D in series. The 246 ELECTRICITY AND MAGNETISM CHAP. moveable coils E and F are connected through a high resistance Rj(to… … Fig. 246. if the difference of potential between M and N is E volts, the current in the moveable coils is ^, R being their resistance together with Rj. The force between each pair of coils B-E, E-C, etc., being pro-IE , ^portional to the current in each, is proportional to -^, and the couple acting…
