Identify the term for a device that limits the amount of current flowing through a circuit.

The correct choice is a fuse, as it is specifically designed to limit the amount of current flowing through a circuit. When the current exceeds a certain threshold, the fuse will blow or melt, opening the circuit and preventing further current flow. This feature is crucial for protecting electrical devices and wiring from damage due to overheating or potential fire hazards caused by excessive current.

Other devices mentioned, like capacitors, transformers, and resistors, serve different functions within electrical systems. A capacitor stores electrical energy temporarily, a transformer changes the voltage level of alternating current, and a resistor limits current flow as well, but through the principle of resistance rather than by disconnecting the circuit. Each plays an important role, but the fuse's critical function of interrupting overcurrent conditions makes it the most appropriate answer in this context.
