Question

What are some causes of brush in static discharges?

1) High voltage
2) Dry air
3) Sharp points
4) All of the above

Answer 1

Brush discharges are caused by factors such as high voltage, dry air, and sharp points, which allow static electricity to build up and create a discharge.

Step-by-step explanation:

Some causes of brush discharges in static electricity include high voltage, dry air, and sharp points on surfaces. High voltage can create a large electrical potential, making it easier for a spark to jump across a gap. In dry air, static charges can build up more easily because moisture in the air normally allows charges to dissipate, and in its absence, the charge stays on surfaces longer. Sharp points concentrate the electric field, making it more likely for a discharge to occur. All of these factors can cause brush discharges in static electricity.
