The corresponding values of voltage on compensator tube and 

 charge annulled are given in Table II, and are illustrated by the curve 

 in Fig 4,

These values were determined experimentally and they showed that 

 the capacity of the tube condenser was, as its construction demanded, 

 practically independent of the voltage applied to it.
