📝 Answer Key

Section A: Short Answer Questions

1. Electric current is the flow of electric charge through a conductor. It is measured in Amperes (A) using an Ammeter.
2. Cells and batteries, generators, solar cells.
3. Positive terminal (carbon rod) and negative terminal (zinc container).
4. The filament glows and produces light when heated by electric current.
5. An electric circuit is a closed path through which electric current flows.
6. • Closed circuit: Current flows (path complete).
   • Open circuit: No current flows (path broken).
7. A switch controls the flow of current, turning it ON or OFF.
8. Battery, bulb, switch, and conducting wires.
9. Conductors allow electric current to pass (e.g., Copper, aluminum).
10. Insulators do not allow electric current to pass (e.g., Rubber, plastic).
