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

SUMMARY
A capacitor is an electrical component that stores energy in an electric field, created by a pair of conductive plates separated by an insulating material, known as a dielectric. The current-voltage (I-V) graph of a capacitor demonstrates a nonlinear relationship, where the current is proportional to the rate of change of voltage across the capacitor. The fundamental equation governing a capacitor's behavior is Q = C * V, where Q is the charge, C is the capacitance, and V is the voltage. Understanding these principles is essential for applications in circuits involving timing, filtering, and energy storage.
