Electrical characteristics of monofilaments in dielectric barrier discharge plasma jets were investigated at atmospheric pressure. It is found that the shapes of monofilaments, the discharge current, the number of discharges, the breakdown voltage and the input power are dependent not only on the Ar flow rate but also on the applied voltage and exhibit complicated behaviors. Especially, the discharge current is irregular and has the oscillating pulses with positive and negative polarities. The influence of wall charges on the above parameters was discussed.
