Chapter 8.5 Voltage Sources

Question 1

What is an electric conductor?

Answer 1

Any material that has free charged particles which easily flow through it when an electric force acts on them

Question 2

What is an electric insulator?

Answer 2

Any material in which charged particles do not easily flow

Question 3

What happens when there is a potential difference?

Answer 3

Charges in the conductor flow from the higher potential to the lower potential
The flow of charge persists until both ends reach the same potential

Question 4

How can you sustain a flow of charge in a conductor?

Answer 4

You must make some arrangement to maintain a difference in potential while charge flows from one end to the other.
Ex: electrical pumps (chemical batteries or generators)

Question 5

How do Electrical Pumps work?

Answer 5

They pull negative charges apart from positive ones, and the energy stored in the chemical bonds is converted to electrical potential energy.

Question 6

By what process do generators separate charges?

Answer 6

Electromagnetic Induction, which takes place at the terminals
