Question
For an experiment in a certain gas to find Townsend's coefficients, the critical threshold
distance for sustained discharge is found to be d=0.7 cm, the value of Townsend's
second ionization coefficient found to be 0.104%, and the steady-state current is found
to be 0.58 nA when d=0.4 cm. If the current after increasing the distance is 1.29
nA, find the percentage of the supply voltage increment in order to keep the field
constant throughout the experiment. (Assume you are working in the linear range as
depicted)
