4 FAQs about [No energy stored after the switch is closed]

What happens when a switch is closed?

What happens when a battery switch is closed?

My physics teacher said that the answer is B, and explained that after the switch is closed the electrons on the right side of the capacitor will move to the other side of the capacitor, and this current will cancel some of the current coming out of the battery, thus reducing the total energy stored in the capacitor.

What happens when a switch is open?

When the switch is open, the equilibrium scenario is that no current is flowing, and the voltage across the capacitor is equal in magnitude to the voltage across the battery: V C = V B.

What happens if a capacitor is closed and let to equilibrium?

The magnitude of energy stored in the capacitor is: E = 1 2 C Δ V 2, so a change in potential difference will cause a change in energy stored. So when the switch is closed and let to equilibrium the resistors will be in series increasing total resistance causing the total current to be less than when it was when the switch was opened.
