Explanation of how a capacitor works?

Click For Summary
A capacitor stores electrical energy in an electric field created between two conductive plates separated by an insulator. When voltage is applied, the capacitor charges, leading to a current flow until it reaches its maximum charge capacity. The I-V graph of a capacitor shows a nonlinear relationship, with current decreasing as the voltage across the capacitor increases. Capacitors are essential in various electronic applications, including filtering and energy storage. Understanding their operation is crucial for effective circuit design.

Could anyone give me a brief explanation of how a capacitor works? What does its I-V graph look like?

Thanks

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
