Q4. The first ionization coefficient for a gas is approximately given by a = Ap e Bye , where p ispressure in Torr and E is electric field in V/cm. The breakdown voltage curve (Paschen Curve) of this gas is given as figure. Suppose that the second ionization coefficient for this gas is =0.002. Find the constants A and B. U (V) U. Min = 350 V p.d (mm.Hg Cm) (p.d) Critical = 1.4
