ained by the dynamo. A series circuit mustwork under high pressure, for each lamp adds its resistance againstthe pressure. It will take ten times the pressure to send the samecurrent in amperes through ten lamps that it does to send it throughone lamp. Hence, suppose one lamp took 60 volts pressure… … V3. Fig. II.—Series-Parallel System current or quantity of electricity flowing must be the same whateverthe number of lamps or motors may be in the series. In a parallel system the volts or pressure is constant, and allmotors, lamps, and other things connected thereto must be made forthat constant…
