【中2理科】直列回路と並列回路の電圧のまとめ｜電気の世界 #13 電圧のまとめ・水流モデル

This is an explanatory video for Lesson 13 of the 8th Grade Science course, "The World of Electricity." [Today's Points] ✔ Voltage is the force that tries to make electricity flow, and in the water flow model, it corresponds to the drop in water level. ✔ A series circuit is like a two-tiered waterfall; the voltage in each section is added up to the whole. ✔ A parallel circuit is like a branching waterfall; the voltage is the same no matter where you measure it. ✔ This is the opposite of the rule for current (same for series, addition for parallel), so distinguish between them.
