This paper deals with the experimental analysis of dielectric barrier discharge (DBD) plasma properties in an atmospheric air pressure enclosed in a cylindrical chamber made of polycarbonate. The DBD was produced in an atmospheric condition with the help of disk electrode geometry (DEG) reactor controlled by ac voltage (0-7 kV) at a frequency of 20 kHz. The current-voltage characteristics were studied. The number of filamentary micro discharges increases in each half cycle with increase in applied voltage. Power dissipation or its consumption in DBD was determined using current-voltage and Lissajous curve method. The electron density of discharge was measured by power balance method, which was found to be in the order of 10¹⁰ to 10¹¹ per cubic centimeter.

DBD, power balance, electron density, micro-discharge, Lissajous curve.
