c d, in order that the dropin a n shall be the same as in c in.If the point n be moved to anypoint in a b, the point m must becorrespondingly moved on c d, in order that there maybe no current flowing though G, and that the proportiona 11 : a b \\ c 111 : c d may still hold good. It is also evident… … 1638 ELECTRICAL MEASUREMENTS. That is, the resistance of a n is to the resistance of c in asthe resistance of n b is to the resistance of in d. From this proportion, it is evident that if a ii, c in, and in dbe known, the resistance of ii b may be readily calculated. This affords a ready means for…
