In corona discharges on van de graff generators, I realize that the gasses in the air are being ionized, which causes a luminescent flame. I know that using leyden jars hightens the milliamps, but the arc of the corona discharge gets smaller. Is there a way I can lower milliamps, and would it make more corona discharge? | ||

You seem to be assuming that the arc gets smaller because the current got larger. Wouldn't it be more likely that the voltage got smaller? The leyden jar or other capacitor will have losses. This shows up as a drop in the voltage. To make the arc longer, increase the voltage. You can do this by increasing the radius of curvature of the sphere at the top. In our design, that would be replacing the soda can with a sphere, the larger the better. |
