The electrical resistance of beds of finely divided graphite and conducting coke have been investigated in the settled and fluidized regions. In almost all cases a maximum in the bed resistance occurs at a gas velocity slightly greater than that required for minimum fluidizing. This has been explained qualitatively by assuming current flow along a continuous network of touching particles the resistance of which is modified by the growth of gas bubbles in the bed.
