學生物理課(九年級: Honor Physics)的下一個單元是電學這是他第一次接觸電學我想買個實驗套組讓他可以親手操作請問各位版大，有無推薦商品？預算無上限，但最好可以透過網路購買，我可能不方帶寶寶出門選購 (希望體積不要太大，不然很佔地方) 國外網站可訂購亦可，過完農曆年才開始教電學這個單元學校課程大綱： <<Electrostatics, current, and resistance. (5 Weeks)>> 電學/電流/電阻 This unit develops understanding about the nature of electricity in the forms of static and current electricity(靜電和電流) so the characteristics of this energy form can be applied to how resistance(電阻) and voltage(電壓) affect electric current. 課程目標： Students should be able to 1. state Coulomb's law.(庫侖定律) 2. solve problems using Coulomb's law for two point charges, involving electric force, charge , distance of separation, Coulomb's constant. (庫侖定律的應用和計算) 3. calculate the net electric force on a point charge due to two other point charges.(點電荷的計算) 4. define electric field.(定義電場) 5. calculate the net electric field at any point on a line containing two point charges.(電場計算) 6. describe the electric field lines for simple charge distributions. 7. describe situations that produce uniform or non-uniform electric fields. (探討均勻電場/非均勻電場) 8. solve problems for a charge in an electric field, involving, force, charge, electric field. (電場對電荷的影響) 9. define the following: electric potential energy, electric potential, electric potential difference. (電力位能/電位差) 10. solve problems for a charge in an electric field, involving electric potential difference, electric potential energy, charge. 11. solve problems for a uniform electric field, involving electric potential difference, electric field, distance between two locations in a field. 12. solve problems for two point charges, involving electric potential energy, charge, distance of separation, Coulomb's constant. 13. calculate the work required to move a charge between two locations in an electric field. (在電場中，要移動電荷所需要做的功) 14. solve problems using the law of conservation of energy for a charge in an electric field, involving speed, mass, charge, distance, work, electric field, electric potential difference. (利用"能量守恆定律"計算電荷在電場中的移動相關數據。含：速度、質量、帶電量、距離、做功、電場、電力位能) 15. apply the principles of electrostatics to qualitatively explain the operation of a cathode-ray tube (CRT).(用電力學解釋陰極射線管原理) 16. solve problems for no more than two point charges, involving electric potential relative to zero at infinity, charge, distance. 17. define electric current.(定義電流) 18. solve problems involving current , time , charge. 19. relate conventional current direction to the direction of electron flow in a conductor. (常規電流/傳統電流和電子流的方向性) 20. define resistance in terms of Ohm's law.(用歐姆定律定義電阻) 21. solve problems involving electric potential difference , current , resistance.
