Ohmslaw the electromotive force is spent partly on each conductor,and in proportion to the resistance overcome. This may be elu-cidated by an actual example. Thus suppose (Fig. 63) an accu-mulator bb of 2-05 volts, joined up to a small lamp l of 3-6ohms resistance, an ammeter a of 0-3 ohm, and let… … Fig. 62 a. 204 ELECTRIC CURRENTS total resistance is 3-6 + 0-3 + 02 = 4-1, hence the current is 2 05 -7- 4-1 = 0-5 ampere. If now a voltmeter be attached to the ends of the lamp, it will indicate that part of the E. M. F. used to drive the current through the lamp alone, viz. 0-5 ampere * 3-6…
