Key Concepts — Quick Reference
This chapter
Circuits & conductors (the must-knows)
| Electric cell | Source of current; two terminals (+ and −); a battery = two or more cells joined |
|---|---|
| Closed circuit | A complete, unbroken loop — current flows and the bulb glows |
| Open circuit | A break/gap anywhere (switch off, loose wire, fused bulb) — no current |
| Conductor | Lets current pass: metals, especially copper; also the human body & tap water |
| Insulator | Blocks current: rubber, plastic, dry wood, glass, air |
Magnets (the must-knows)
| Two poles | Every magnet has exactly two poles — North and South; poles are inseparable |
|---|---|
| Pole rule | Like poles repel; unlike poles attract |
| Directive property | A freely suspended magnet rests in the North–South direction (basis of a compass) |
| Magnetic materials | Attracted by a magnet: iron, nickel, cobalt (and steel) |
