What is a capacitor used for?
Capacitor Definition: A capacitor is defined as a device with two parallel plates separated by a dielectric, used to store electrical energy. Working Principle of a Capacitor: A capacitor accumulates charge on its plates when connected to a voltage source, creating an electric field between the plates.
How does a capacitor work?
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
