em. Take two cells of the battery inseries, and from the wires a b connect the resistances and the lampin parallel, and the voltmeter in parallel, the ammeter in series. Itwill be noticed that wherever the voltmeter may be coupled acrossbetween the mains the pressure is the same. Disconnect the… … Fio. 47.—Experimental Parallel Circuit be 2 amperes, with one of them on i ampere, and by varying theresistances any current between i and 2 amperes obtained ; yet thevoltmeter remains steady at 4 volts. In the series system, if the pressure is constant at the ends of thecircuit, the current varies…
