Paschen's curve for air
WebThe Paschen's law is considered the breakdown curves of the glow discharge and is described by V p = f (P.d), i.e. the breakdown voltage depends on the electrode gap (d) and the gas pressure (P) [5,6]. The Paschen curve can be obtained by computing the voltage required for the process of electron emission and multiplication to WebThe constants a and b depend upon the composition of the gas. For air at standard atmospheric pressure of 101 kPa, a = 43.6×10 6 V/ (atm·m) and b = 3.62x10 5 / (atm·m). …
