What term describes the ability of a device to store electrical energy?

The ability of a device to store electrical energy is referred to as capacitance. This property is associated with capacitors, which are components specifically designed to hold an electric charge. Capacitance is defined as the amount of electrical charge a capacitor can store per unit voltage. It is measured in farads (F) and plays a crucial role in various electronic circuits, often used in applications like filtering, timing, and energy storage.

In contrast, resistance pertains to how much a material opposes the flow of electric current, which does not involve energy storage. Inductance is related to coils and inductors, describing the property of a conductor to generate a magnetic field when an electric current passes through it, again not capable of storing energy in the same manner as capacitors. Conductance, on the other hand, measures how easily electricity flows through a material, serving as the reciprocal of resistance. Therefore, capacitance is the specific term that accurately describes a device's capacity to store electrical energy.
