An elementary book on electricity and magnetism and their applications . iple latter term was coined inthe early days of arc total resistance of a cir-cuit made up of parts connectedin series is equal to the sum ofthe individual resistances of allthe parts. The total resistance of a cir-cuit made up of parts connectedin parallel is equal to the recip-rocal of the total conductanceof the circuit, and the total con-ductance is equal to the sum of the individual conductances ofthe parts. When part of the total circuit is made up of conductors inparallel and part of conductors in series, it is necessary tocalculate the joint resistance of the first part and then addthat to the resistance of the remainder of the circuit which isin series with the branched portion. It is easily seen thatthe joint resistance of conductors in parallel is equal to the resist-ance of a single conductor by which the compound circuit mightbe replaced without changing the total resistance of the that in the circuit shown in figure 26 the resistances. Fig. 26. 7>^OHMS— Compound circuit. ELECTRIC CIRCUITS AND FLOW OF ELECTRICITY 57 in ohms of the different parts are as marked; then the resist-ance of the complete circuit is 6 + 34 1 1125^T5 or 12 ohms. If the voltage developed by each of the two cells, which arerepresented by the usual sign (||), is volts, the current 2 4 flowing through the circuit is —— = amperes. This would be analogous to a system of water piping betweentwo tanks, as seen in figure 27.
