伝導

1. Origins, structure, and basic meaning

• Structure: 伝導 (でんどう) is conduction of heat or electricity through a material. It appears as thermal transfer and an electrical property.
• Basic usage: An experiment observes heat moving through metal; a table compares electrical conduction across materials.

2. Common pitfalls and similar expressions

• Thermal transfer observed and electrical behavior compared
  • 熱が伝導する describes heat transfer, while 電気伝導 forms the concept of electrical conduction. Distinguish this physical process from passing information between people.
