When two (or more) resistances are in parellel, then the resitence provided by the two together is given by reciprocal addition, i.e. 1/(total resistence) = (1/resistance1) + (1/resistance2).

Wire resistance

The volume resistivity of a prismatic sample is calculated by the equation (cross-section)*(resistance)/(length). Common units are Ω⋅cm, but other units may also be used.
