CIRCUIT THEORY
REVIEW QUESTIONS.

1. Why must energy be expended by an electric "charge separator," which removes electrons from neutral atoms?

2. How does charge separation in an electric battery differ from charge separation by rubbing a glass rod with a silk cloth?

3. Why does a potential difference exist between two electric conductors possessing unlike charges?

4. Why are we more concerned with the electric field between unlike charges in electric circuits than we are with the repulsion between like charges which we can demonstrate in electrostatics?

5. What is the significance of the arrows on the sketch of electric lines of force between two parallel plates?

6. What characteristic of an electric field is referred to by the term electric field intensity?

7. What is meant by the potential gradient of an electric field?

8. How are electric field intensity and potential gradient related in the case of charged parallel plates?

9. What factors govern the flux density of the electric field between the charged parallel plates?

10. Draw a sketch showing the equipotential surfaces in the electric field between two charged concentric conductors.

11. Define a displacement current.

12. What is meant by polarized atom?

13. What type of atoms can become polarized?
