Question
A parallel-plate capacitor is charged by con-necting it to a battery.
If the battery is disconnected and the sep-
aration between the plates is increased, what
will happen to the charge on the capacitor
and the electric potential across it?
1. The charge and the electric potential de-
crease.
2. The charge increases and the electric po-
tential remains fixed.
3. The charge and the electric potential in-
crease.
4. The charge remains fixed and the electric
potential decreases.
5. The charge and the electric potential re-
main fixed.
6. The charge remains fixed and the electric
potential increases.
7. The charge decreases and the electric po-
tential increases.
8. The charge increases and the electric po-
tential decreases.
Explanation / Answer
A parallel-plate capacitor is charged by connecting it to a battery. If the battery is disconnected and the separation between the plates is increased, what will happen to the charge on the capacitor and the electric potential across it? when battery is disconnected the charge remains constant. when the separation between the plates is increased potential increases hence option 6 is correct. 2. 3. 4. 5. 6. The charge remains fixed and the electric potential increases. 7. 8.
