The condition confrontedmay be compared with an instance where a big engine is called for topump water with pipes which present the downside of greatfriction. We get a large voltage by attaching the cells in series, i.e., by signing up with the unliTce elements together, the zinc of one cellto the card on of the following. For electro-therapeutic use, allgalvanic batteries are attached in series. If we wish to heat up a platinum cable for cautery job, wewill have but a small resistance; so we generate a large amperageby linking in multiple or parallel. This is done by joiningthe liTce aspects, i.e., the zinc of one cell to the zinc of the next. It is really essential that the electro-therapeutist under-stands completely the distinction in between batteries attached inseries as well as batteries attached in multiple or parallel. A battery organized in series is displayed in the followingdiagram:– Text Showing up After Picture: Zinc. Carbon. Zinc. Carbon. Zinc. Carbon. Fig. 2.– Cells in series. Unlike aspects are attached in series. 24 ELECTRO-THERAPEUTICS. If each cell in the above battery offers a pressure of onevolt and also one ampere in amount, we will have iliree volts andbut one ampere. A watt= volts times amperes, for this reason 3 v. times 1 a. ^ 3watts. This diagram reveals a battery connected in numerous orparallel.

The adjustment of this break requires some practice, as some coils call for a different change to obtain thebest outcome. As excellent a technique as any type of is the following:– Both screws being sagged, and also the platinum facesC C being nicely smoothed and also flattened with a great documents, the top screw B is relied on the right until theplatinum contacts are practically touching– leaving a spacebetween equal to the density of a seeing card. Theclamping nut on B is currently run up against the pillar, so asto prevent this screw turning while the coil operates. Text Appearing After Image: Fig. 30.

As the tension is increasedthe outcome of the coil raises, but the interrupter worksmore gradually owing to that the core of the coilmust become a lot more very magnetised before its pull uponthe armature suffices to divide the platinumcontacts.
