UNIT OVERVIEW

This revision covers the main topics from Term 3:

• Electrostatics – Forces between charges and electric fields
• Electromagnetism – How electricity and magnetism connect
• Electric Circuits – Energy, power, and electricity costs
• Acid-Base Reactions – pH, neutralisation, and titrations
• Redox Reactions – Electron transfer and oxidation numbers

Why these topics matter:

• Lightning and static shocks come from electrostatic forces
• Power stations use electromagnetic induction to generate electricity
• Understanding kilowatt-hours helps you read your electricity bill
• Antacid tablets use acid-base reactions to treat heartburn
• Batteries and rust both involve redox reactions
