| # | Answer |
|---|---|
| 1 | Electricity is the movement of electric charge. |
| 2 | A circuit is a complete path for electricity to flow. |
| 3 | An insulator is a material that does not let electricity pass through easily. |
| 4 | A conductor is a material that lets electricity pass through easily. |
| 5 | Copper is a common conductor. |
| 6 | Plastic is a common insulator. |
| 7 | A battery is often used in a simple circuit. |
| 8 | A switch opens or closes a circuit to stop or allow the flow of electricity. |
| 9 | Electricity can flow through the circuit. |
| 10 | Electricity cannot flow through the circuit. |
| 11 | Wires connect the parts of a circuit and allow electricity to flow. |
| 12 | It gives off light when electricity flows through it. |
| 13 | A plastic object is safer to touch with wet hands because plastic is an insulator. |
| 14 | It is dangerous because electricity can pass through your body and cause injury. |
| 15 | A battery provides electrical energy for the circuit. |
| 16 | Check whether the circuit is complete. |
| 17 | Metal wires are used because metals are good conductors of electricity. |
| 18 | It can cause an electric shock. |
| 19 | Rubber is used because it is an insulator and helps prevent electric shocks. |
| 20 | The circuit must be complete so electricity can flow from the battery through the bulb and back again. |
