Ordinarily Ccan be neglected, as compared with the capacities ofAC and the cable, in which case, by transposition,Cb=(V—V/)Ca+V/. Conductors of telephone cables are measured for capacity with the… … Fig. 9.as shown. This is virtually a Wheatstone bridge, in which one of the wires,71, is one of the arms of same.
