Mini-Quiz: Detection of Static Electricity

by Ron Kurtus (revised 22 January 2009)

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



1. Why is finely ground pepper used to detect static electricity?

Finely ground pepper is hot and causes static electricity sparks

Pepper has a strong negative (−) charge

Finely ground pepper is very lightweight and is easily attracted to an electrical object

2. When do the leaves of an electroscope move apart?

When they become charged with static electricity

When they get opposite charges

They are always spread apart unless charged

3. Why would a company buy an expensive electrostatic locator?

When the static electricity is Alternating Current (AC)

When the less expensive methods aren't sufficient

As part of an effort to reduce air pollution

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.
