Mini-Quiz: Causes of Static Electricity

by Ron Kurtus (revised 28 November 2008)

Take this Mini-Quiz to check your understanding of the lesson material.



1. How does rubbing materials together cause static electricity?

Friction from rubbing causes electrons to deposit on the other material

The adhesive force between the materials separates the electric charges

Rubbing creates friction that shoots off sparks

2. Do all materials cause static electricity equally?

Yes, since all materials have positive and negative charges

Materials have nothing to do with static electricity

No, certain combinations of materials work best to cause static electricity

3. How could the piezoelectric effect used to show static electricity?

Show that opposite charges are attracted to end of pressed crystal

Press on the crystal until it explodes, sending off charged particles

The piezoelectric effect has nothing to do with static electricity

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
