When voltage supply is removed from a parallel plate capacitor, why does the charge remain as before?

A capacitor is an electronic device that stores and releases electrical energy. It is made up of two conductive plates separated by an insulating material called a dielectric.
When a voltage is applied to a capacitor, one plate accumulates a positive charge while the other accumulates a negative charge. This creates an electric field between the plates, and the capacitor stores energy in this field. When the capacitor is connected to a circuit, it can release this stored energy.
There are many different types of capacitors, including ceramic, electrolytic, film, and tantalum capacitors. Each type has different properties and is used for different purposes.
The unit of capacitance is the farad (F). However, capacitors are typically measured in smaller units such as microfarads (μF) and picofarads (pF).
The capacitance of a capacitor can be calculated using the formula C=q/V, where C is capacitance, q is the charge on the plates, and V is the voltage applied to the capacitor. The capacitance also depends on the size and distance between the plates, as well as the type of dielectric material used.
