Automotive horns get power from a/an ________.

Explanation:
Horns draw more current than a simple switch can safely handle, so the circuit uses a relay. The horn switch on the steering wheel only energizes the relay coil with a small, low-current signal. When the coil is energized, the relay closes its high-current contacts and connects the horn to the battery, delivering the full current needed for the horn. This protects the horn button and steering wiring from heavy current, reduces voltage drop, and ensures reliable operation under load. The fuse is there to protect the circuit, the battery provides the power source, but the actual controlled power to the horn runs through the relay, which is why the relay is the correct answer.
