Cells are in parallel when one primary wire running the length ofthe battery, is connected to each and all of the zincs, while the other primaryis similarly attached to all of the carbons. We have shown how amperage or current strength can be modified byconnecting cells in multiple or parallel, thus greatly increasing the

This way of connecting cells, to get a current of great strengthor amperage, and little pressure or voltage, is used in the cautery batteryfor cautery work. The accompanying sketch shows the scheme of wiring of a battery ofsix cells, arranged in multiple or parallel for volume and also showshow such a multiple battery is connected, in series, with a milliamperemeter, rheostat, cautery cables and cautery knife. How do galvanic and cautery currents differ? Galvanic currents proceed from batteries connected in series, andare different from cautery currents in that their voltage is high and theamperage is low, whereas the latter have low voltage and high amperage.The cautery currents are derived from batteries connected in parallel. What is meant by ^*in shunt?^ Shunt means
