Lesson 1: Fundamentals of Electricity

Question 1

electric force

Answer 1

Acts on two or more electric charges

Question 2

Atoms

Answer 2

small particles of matter that give substances the various properties that we experience

Question 3

protons

Answer 3

positively charged

Question 4

electrons

Answer 4

negatively charged

Question 5

neutrons

Answer 5

uncharged

Question 6

Are atoms positive, negative or neutral charged?

Answer 6

Atoms are usually neutral charged

Question 7

conductors

Answer 7

allow electric charge to be moved (“conducted”) through the material when an electric force is applied. An example of a conductor is a metal such as copper (which is widely used in electrical circuits for its highly conductive characteristics).

Question 8

insulators

Answer 8

tightly bound atoms that create material that stop the flow of electrons such as plastic, glass, air and water.
