Answer 7

Resistance

Question 8

The rate at which energy is transformed from one thing to another ?

Answer 8

Power

Question 9

Materials that allow current to flow are called ?

Answer 9

Conductors

Question 10

Materials that do not have free electrons (electrons cannot flow) are called ?

Answer 10

Insulators

Question 11

Insulators can build up static charges as _______ do not flow freely in an insulator

Answer 11

Electrons

Question 12

Why are metals good conductors ?

Answer 12

Metals have free electrons in their outer valence shell, free electrons carry a charge therefore a current can flow
