that case, if the resistance of the leading wires is alsoneglected, that of the galvanometer is given by g= (5) (2) Thomsons method. This is an application of the principle of the Wheatstonebridge, similar to that described in Experiment XII. The gal-vanometer is disposed, as shewn in Fig. 43,… … potential, then a current will pass between these points whenthe key is depressed, and a consequent alteration in the deflec-tion of the galvanometer will occur. If, however, the resistances a, b, and c are so adjusted thatC and B are at the same potential, it is quite immaterialwhether the key is…
