Semester 2 Science Test

Which if the following is NOT an example of how static electricity is transferred?

• Attraction
• Conduction
• Friction
• Induction

A static discharge is different from an electric current because a static discharge:

• Is a flow of electrons
• Lasts for only a fraction of a second
• Results from a force being exerted on the electrons

 How do charges flow?

• Places of higher amounts of electrons to places of lower amounts of electrons.
• Places of lower amounts of electrons to places of higher amounts of electrons.
