trength when the internal resistanceis the principal one to be overcome. For instance,call the electro-motive force (E) of a single cell1 volt, its internal resistance 5 ohms, and let theplates be connected by a short, thick wire, whose resistance may be regarded as nothmg; then F 1C = — = — = .2… … 230 ELECTRICITY AND MAGNETISM. when there is no external resistance, the current increases asthe size of the plates is increased. The same is approximatelytrue in case the external resistance is very small in comparisonwith the internal resistance. Again, let E = 1, r= 5 ohms, as above, but the…
