But, the resistors also have the same potential drop. Since E has a smaller decay constant, it is less likely to decay into F and since F has a larger decay constant it is more likely to decay into G. Hence, the amount of F is always small as the rate of decay of F is greater than rate of formation of F. Alternatively, greater decay constant means lower half life(inverse relation), hence E has a greater half life and F has a lower half life, thus E decays less often to form F while F decays quickly form G. Therefore, F is always small as again rate of decay of F is greater than its rate of formation.
