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

A fuse cannot be used to store an electrical charge because its primary function is to protect an electrical circuit by interrupting the flow of current in the event of an overload or short circuit. It operates by melting a metal strip when the current exceeds a predetermined level, thereby preventing damage to other components in the circuit.

In contrast, a capacitor stores electrical energy in an electric field and can release this energy when needed. A battery stores energy chemically and can provide a steady power supply over a longer duration. An inductor, while primarily storing energy as a magnetic field when current flows through it, can indeed hold energy similar to capacitors but in a different form. Thus, the fuse stands out as a safety device rather than a storage element for electrical charge.
