100 CHAPTER 5 1957 Guide Following the electrical analogy, when there is a thermal current flowing through several resistances in series, the resistances are additive: Rt = Ri + Rt + 72, * + Rb (7) Similarly, conductance is the reciprocal of resistance, and for heat flow through several resistances in parallel, the conductances are additive: Ct Rt 72, + 72, + 72, + " ' + 72
