Effect of clearance and displacement of attracted disk, and also of a certain arrangement of conducting hoops, upon the constant of an electrometer
C. Snow · Bureau of Standards Journal of Research · 1928
Formulas are here derived for the force upon the attracted disk of an absolute electrometer.These take account of the clearance between attracted disk and its guard plane, their relative displacem ent, and the separation of the plates.The effect of usirlg a set of conducting hoops to compensate for the finiteness of the movable plate is also computed.
