it will be evident that for every volt electromotive force added to the circuit there are added to the same circuit, 2 ohms resistance. For example, with i cell, ^—-- = | ampere, or - 2 ohmj with 1,000 cells, L^^^^J^^ =i ampere.2,000 ohms Cells in Opposition.—In Fig. 15 is shown a set of 6 cells, 2… … 2 3 4 CELLS IN OPPOSITION. reference to the arrangement of the posi-tive (-f-) and negative (—) signs over the ^ / ~ ^+cells, that cells i and 2 are opposed tocells 3, 4, 5 and 6. The effect of this isthat the electromotive force of cells, i and2, offsets, or neutralizes, the electromotive ^force…
