24 RICHARDSON'S BLUEBOOK OF PROJECTION will raise the total voltage by its own voltage. Parallel connection will not alter the voltage but will raise the current to any desired part of the full capacity of the additional cells. Remember that voltage acts only between the negative and positive of the same power source, and that the positive attached to one power source has no affinity for the negative attached to another power source. ^ Moreover, neither positive nor negative has any affinity for the earth, save that the earth may furnish it a path to opposite polarity of the same power source. The idea that current generated by a dynamo seeks to escape from it, or from the wires connected to it, into the earth, is wrong but for the one exception noted above. Figure 7 Ampere (78) This term is used to denote quantity or volume. Amperes represent the volume of current flowing in a circuit, exactly as gallons per second represent the quantity of water flowing through a pipe. How Work Is Accomplished (79) Work is performed by voltage causing volume (current) to flow against electrical friction. When water, under pressure turns a wheel, it is not the water that is consumed, but its pressure. (80) The higher the pressure or volume the greater the amount of work any given volume of either electricity or water may be made to perform. However, it is not the volume, but the pressure which is consumed in performing work.
