onnected inparallel, and then in series with the battery wires. If the re-sistance of A is equal to that of B, the conductance will alsobe equal and the current will divide, one-half flowing through A and the other half throughB. Since the total area of theconducting circuit has beenincreased, the… … ItS.—Two Unequal Resistancesin Series. been doubled, and thehalf that of A or B. Thus Joint resistance = .-, of 10 or 5 ohms. With three equal re-sistances in parallel the joint resistance will be .t the value ofone of the resistances. To Find the Joint Resist-ance of any Number ofEqual Resistances…
