用法筆記

This sense is technical and appears almost exclusively in electrical engineering contexts. In general conversation, reactor without context nearly always means a nuclear reactor.

常見錯誤

❌The electrical reactor changed the voltage.
✅The electrical reactor helped limit the current in the circuit.
💡A reactor controls current flow by opposing changes; it does not directly change voltage.
