One tool for checking static electricity is Electroscope Circuit to Measure Electrostatic Charge. Static electricity happen when object have unbalanced electric charges. Electroscope help to know if static electricity is there and it is how much. It just simple conductor. When something touches it then electroscope charge changes and react. This movement show what charge […]
