Fig. 136. If there are several cells in compound circuit, AB representsthe total resistance, and AD the total E.M.F. of the battery.The line of potential will not then be DC, but a broken linewhich rises at each cell. Thus, supposing we have threecells, the line of potential will be given by E, F,… … Fig. 137. The potential gradient gives us only potential differences,and not the absolute potential at any point, If the cell andcircuit be all insulated, the potential at some parts will be -f,and at other parts —, depending on the capacity of thevarious parts of the circuit. If we connect the…
