We evaluated the electrical resistivity of Pd hydride without electrical contact. An alternatingcurrent susceptometer was used to measure the electrical resistivity. When columnar samples wereused, it was possible to determine their relative electrical resistivity was obtained after simpleanalysis. The relative electrical resistivity increased monotonically with increasing hydrogenconcentration in the Pd rod. At lower hydrogen concentrations, the obtained relative electricalresistivity was approximately the same as that reported previously, indicating that thealternating-current susceptometer correctly measured relative electrical resistivity. At higherhydrogen concentrations, the results differed from the values reported previously. Sample shape andgeometry must be considered to obtain accurate values at higher hydrogen concentrations.
