Which of the following cannot be used to store an electrical charge?

A fuse is designed primarily as a safety device that protects an electrical circuit by breaking the connection when the current exceeds a certain level. It does this by melting an internal conductor, effectively stopping the flow of electricity. Unlike a dielectric, capacitor, or battery, a fuse does not have the ability to store an electrical charge.

In contrast, a dielectric is a non-conductive material that can store electrical energy when placed in an electric field, while a capacitor is specifically designed to accumulate electric charge and release it when needed. A battery, on the other hand, stores energy in the form of chemical potential and converts that energy into electrical energy when connected to a circuit. Each of these components has the capacity for storing energy in some form, establishing why the fuse stands out as the option that cannot store an electrical charge.
