Conductors and insulators
| Conductors (current passes) | Insulators (current does not pass) |
|---|---|
| Iron, copper, aluminium, steel — most metals; a coin, a safety pin | Plastic, rubber, wood, glass, paper, cotton thread, chalk |
Test it: make a circuit with a cell, a bulb and wires, leave a gap, and put the object in the gap. If the bulb glows, it is a conductor.
Safety: our body conducts electricity. Never touch switches with wet hands or play near power lines.
Goes with NCERT Curiosity Class 7, Ch 3 “Electricity: Circuits and their Components”.
