Question

14. You slide a slab of dielectric between the plates of a parallel-plate capacitor. As you do this, the potential difference between the plates remains constant. (This can happen if plates remain connected to the same battery.) What effect does adding the dielectric have on the charge on the capacitor plates? A. The charge increases. B. The charge remains the same C. The charge decreases D. not enough information given to decide 15. Each capacitor in Figure 5 has a capacitance of 2.0 F What is the potential difference Vbc between points b and c if Vab = 100 V? A. 30 V B. 40 V C. 50 V D. 60 V E. 70 V at Figure 5

Explanation / Answer

Ans 14. A. Charge increases.

Explanation:

Introducing a dielectric between plates increases the capacitance of the capacitor. This in turn will increase the charge on plates for same voltage.
