When used with cells, they are all used, andthe voltage cannot be controlled as in the case of the cell selector, which issometimes a disadvantage where there is very little resistance to overcome,as the current of 5 milliamperes from a battery of 50 cells with a pressure of75 volts behind it, is much more painful about the face than the samestrength of ctirrent, from 10 cells with only 15 volts behind it.
