#acl reardon:read,write,delete,revert,admin FacultyGroup:read,write All:read = Cottrell Precipitator 5B30.60 = Precipitator located in [[ElectrostaticsCabinet]], A2 Toepler-Holtz generator located in [[ElectrostaticsCabinet]], A3 Light a cone of incense and place the incense in the precipitator. Discharge Toepler-Holtz generator: grasp insulating handles and put terminals (2cm diameter metal balls) in contact with each other. Connect the electrodes at the end of the tube to the Toepler-Holtz generator. Separate the terminals of the Toepler-Holtz by 5 cm. Wait until the tube fills with smoke. Crank the generator (there should be no sparking between the terminals). The smoke should clear ("precipitate"). Discharge Toepler-Holtz generator--you will likely see a fat spark between the two terminals as you do this. Do not put your hands near the terminals before you discharge them--the spark from the Toepler-Holtz can be painful. {{attachment:CottrellPrecipitator5B3060.jpg}} [[ElectricFieldsAndPotential| Electric Fields and Potential]] [[Demonstrations]] [[Instructional|Home]]
