Closing the switch shows whether energy is stored or not

What happens to the current when the switch is closed?

When the switch is closed, it provides a direct (low resistance) path for current to flow through. How do you find the current when the switch is closed? Can a circuit work without a switch?

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 is a closed switch?

A closed switch is one that provides a direct (low resistance) path for current to flow through.

What happens when a switch is open in a circuit?

No current can flow if the circuit is broken, for example, when a switch is open in the circuit, current will not flow in any part of circuit as circuit is open and there is no closed path available for charge to flow.

What happens if a switch is not present?

If a switch is not present, current will not flow through the circuit. This is functionally equivalent to a switch always being in its “off” state. Without a switch, there is no way to complete the circuit and allow current to flow.

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.
