The U.S. Navy offers enlistees a chance to serve in more than 60 different job fields. One of the largest job fields, or ratings, in the U.S. Navy is hospital corpsman, or Navy corpsman..
Cell voltage. The standard electrical potential of a cell can be determined by the use of a standard potential table for the two half cells involved. The first step is to identify the two metals reacting in the cell. Then one looks up the standard electrode potential, E0, in volts, for each of the two half reactions.
Each cell is made up of a set of positive and negative plates immersed in a dilute sulfuric acid solution known as electrolyte, and each cell has a voltage of around 2.1 volts when fully charged. The six cells are connected together to produce a fully charged battery of about 12.6 volts.
