a return, as in Fig. 8. Battery d would require to be twiceas big as battery a, for it has twicethe work to do, twice the quantity ofelectricity to supply. Battery c c wouldbe same size as a, but would requireto give twice the pressure — that is,supply same current of electricitythrough two lamps… … Fig 7. Battery d d would require to be capable of giving the samequantity of current as battery b, for the lamps are two in parallel as in battery b, and would have to givetwice the pressure of battery b, forthere are two series of lamps. The pressure required is propor-tional to the number in…
