The electrical resistivity of liquid lead was measured between its freezing point,tF= 327.5 and 800°C with a relative accuracy better than 2.5 × 10−2%. The resistivity was found to be a concave function of temperature of the formp(X)=a1.X+a2.[1 - exp(-a3.X)] +po, whereX=t-tF, in the whole range studied. The temperature coefficient of resistivity is a continuous and decreasing function of temperature. A possible explanation of the observed phenomenon is suggested
