Mini-Quiz: Electrical Charges

by Ron Kurtus (revised 19 June 2016)

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



1. Which sub-atomic particle has no electrical charge?

They all have electrical charges

Anti-matter

The neutron

2. Why does the electrical field flow from (+) to (−)?

Because (+) is bigger than (−)

It is just a convention that scientists agreed upon

It's just there

3. Why do things stick together in static electricity?

They only stick if one is made of matter and the other is made of anti-matter

The (+) charges on one material attract the (−) charges on the other object

Like charges attract

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.


Be good at taking tests
