Electricity Exit Ticket
| # | Answer |
|---|---|
| 1 | Electricity is the flow of electric charge. |
| 2 | A conductor. |
| 3 | An insulator. |
| 4 | Negative charge. |
| 5 | Positive charge. |
| 6 | A battery or power source. |
| 7 | It opens or closes the circuit to stop or allow current to flow. |
| 8 | A circuit. |
| 9 | Current can flow through the circuit. |
| 10 | Current cannot flow through the circuit. |
| 11 | The rate at which electric charge flows. |
| 12 | Amperes, or amps. |
| 13 | Volts. |
| 14 | Voltage. |
| 15 | Ohms. |
| 16 | It slows or opposes the flow of current. |
| 17 | Current increases. |
| 18 | Current decreases. |
| 19 | Ohm's law. |
| 20 | Voltage equals current multiplied by resistance. |
| 21 | The bulbs become dimmer. |
| 22 | The voltage is shared among more bulbs, so each bulb gets less energy. |
| 23 | Each branch has the same voltage as the source. |
| 24 | So devices can work independently and receive full voltage. |
| 25 | The other branches usually keep working. |
| 26 | The whole circuit stops working. |
| 27 | The rate at which electrical energy is used or transferred. |
| 28 | Watts. |
| 29 | Current and voltage. |
| 30 | 24 watts. |
| 31 | 3 amperes. |
| 32 | 8 volts. |
| 33 | 2 ohms. |
| 34 | Current, using an ammeter. |
| 35 | Voltage, using a voltmeter. |
| 36 | So all the current passes through the meter. |
| 37 | So it measures the potential difference across a component. |
| 38 | A buildup of electric charge on an object. |
| 39 | A sudden discharge of built-up electric charge in the atmosphere. |
| 40 | The tree can attract lightning and increase the chance of being struck. |
| 41 | Charges separate within clouds and between clouds and the ground, creating lightning when the difference becomes large enough. |
| 42 | It provides a safe path for electric charge to reach the ground. |
| 43 | Connecting a system to Earth so excess charge can safely move away. |
| 44 | Water can conduct electricity and increase the risk of shock. |
| 45 | Wet skin lowers resistance, allowing more current to flow. |
| 46 | Conventional current is often shown flowing from positive to negative, even though electrons move from negative to positive. |
| 47 | Current is produced by the movement of electrons through the wire. |
| 48 | Metals are good conductors, so they allow electric charge to move easily. |
| 49 | A parallel circuit, because each bulb has its own branch and one failure does not stop the others. |
| 50 | In a series circuit, the same current flows through all components and voltage is shared, but one break stops the whole circuit. In a parallel circuit, current splits among branches, each branch gets the full voltage, and the circuit is more reliable because one branch can fail without stopping the others. |
