Mission SE4: Charging by Contact and Grounding

Mission SE4 pertains to the process of charging by contact (i.e., conduction) and the process of grounding. Students will need to be able to predict which direction electrons will flow during each process. The mission consists of 34 questions organized into 10 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
 

Learning Outcomes

• The student should be able to describe the method of contact charging, identify the result of contact charging, and explain contact charging in terms of the conservation of charge and the direction of electron flow.
• The student should be able to describe the grounding process and explain grounding in terms of the direction of electron flow.

• What happens when an object is charged by conduction using a negatively-charged object?
• What happens when an object is charged by conduction using a positively-charged object?
• What charge will an object subsequently acquire when charged by contact?
• What is grounding?
• What is required in order for an object to be grounded?
• What happens (at the atomic level) when a negatively-charged object is grounded?
• What happens (at the atomic level) when a positively-charged object is grounded?
