3 Conductors and Charge

Objectives

➜ ➜ Explain how electric charges concentrate at a point in a conductor.

➜ ➜ Explain how a potential difference is generated between two charged
objects and how a potential difference can become large enough to
cause a spark (including lightning as an example of discharge).

Vocabulary

• Atom • Electron • Potential difference

• Attract • Force • Repel
• Conductor • Insulator • Static electricity

• Discharge • Polarise • Transfer
• Electric charge
