1. What is the relationship between charge and mass when a metal becomes charged, and assess whether the mass change is significant?
2. How do grounding systems prevent static buildup in fuel trucks, what are the dangers without grounding?
3. Why do electrons transfer charge instead of protons or neutrons, and how does this affect circuit and device design?
4. Why does a charged balloon stick to a neutral wall due to polarization? Compare the interaction with a conductor vs an insulator.
5. How do positive and negative charges behave differently in an electric field?
6. What are the effects of changing electric field direction or strength in applications like capacitors?
7. Compare electric and gravitational field in terms of strength, range and forces and evaluate situations where both fields affect objects.
8. Can insulators be charged by induction, under what conditions does this happen and what are alternative methods for charging insulators?
9. What is corona discharge around conductors, especially sharp points?
10. How does electric field concentration cause ionization and what are its practical uses for problems?
11. What causes Lichtenberg figures form after lightning strikes, why don’t they always appear?
12. How do lightning rod protect buildings, what is the role of pointed rods in attracting discharge?
13. How can lightning rod design and placement be optimized for better protection?
