Electricity Practice Worksheet
| # | Answer |
|---|---|
| 1 | Electricity is the movement of electric charges through a material or space. |
| 2 | An electron carries a negative electric charge. |
| 3 | Protons have a positive charge. |
| 4 | A common source of electricity at home is a battery or wall outlet. |
| 5 | A circuit is a complete path that allows electric current to flow. |
| 6 | When a circuit is broken, electric current stops flowing. |
| 7 | An insulator is a material that does not let electricity flow easily, such as rubber or plastic. |
| 8 | A conductor is a material that lets electricity flow easily, such as copper or aluminum. |
| 9 | Metal wires are used because metals are good conductors of electricity. |
| 10 | A battery provides electrical energy that pushes charges through the circuit. |
| 11 | A switch opens or closes a circuit to stop or allow current to flow. |
| 12 | A light bulb converts electrical energy into light and heat. |
| 13 | The bulb will go out because the circuit no longer has a power source. |
| 14 | Electric current is the flow of electric charge through a circuit. |
| 15 | Water can conduct electricity and increase the risk of electric shock. |
| 16 | In a series circuit, there is one path for current. In a parallel circuit, there is more than one path. |
| 17 | A parallel circuit is better because each branch has its own path for current. |
| 18 | You can use a stronger battery or reduce the resistance in the circuit. |
| 19 | Resistance is a force that slows the flow of electric current in a circuit. |
| 20 | Electrical safety is important because it helps prevent shocks, burns, and damage to equipment. |
