Name That Charge

O

Do you think you understand charging methods? Well maybe you do. But one thing is for sure - this little Interactive is going to quickly challenge your understanding ... and improve it if it's not quite complete. Seven electrostatic charging situations are presented and your mission is to determine the charge that each object would acquire as the result of the process. Game-like features track your progress through the exercise. Animations of the charging process are provided for each situation. With the Help Me! button, question-specific help is just a mouse-click away.
