where i is the value of the corona current per unit of electrode length.
At the wire cross-section diameter d = 0,6 mm, cylinder diameter D = 100 mm, wire potential U = -25 kV and corona current per unit of electrode length I = 0,5 mA/m space charge density near the wire was 170[micro]C/[m.
The researchers generate the corona current -- a stream of ionized air -- by placing a high-voltage electrode near a conducting surface such as a recently painted metal panel.
