ABSTRACT THE total potential across a short arc discharge is normally a few tens of volts, and the cathode and anode falls, the regions of high field close to the electrodes, account for a
large proportion of this. The small thickness and high current density in the cathode and anode fall sheaths make measurements of potential in these regions very difficult. In the past, the
sum of the electrode potential falls has been found either by extrapolating voltage-length plots to zero length, or by measuring the arc voltage on an oscilloscope just before approaching
electrodes contact1, but it has not been possible to determine their individual contributions unambiguously. The thickness of these regions has also remained a matter of conjecture. Access
