Electricity & Circuits
| Question | Answer |
|---|---|
| Electricity | Flow of electrical energy from one place to another. |
| Circuit | Path that can allow electricity to flow, if closed. |
| Circuit | Materials that electricity can easily flow through (e.g., metals). |
| Insulator | Materials that electricity cannot easily flow through (e.g., wood, plastic, rubber). |
| Volts | Measure of potential energy between two points in a circuit or in a battery. |
| Resistor | Component of a circuit that reduces the amount of electricity flowing through it. |
| Potentiometer | A variable resistor that is a component of a circuit that can control the amount of electricity flowing through it using a knob or a slider. |
| Series circuit | Circuit in which all the components are in a chain so that the current has only one path to take. |
| Parallel circuit | Circuit in which the components are connected in parallel to each other; each component has its own separate branch. |
| Capacitor | A device that stores electrical energy. |
| Transistor | A component of a circuit that regulates the flow of electricity (can amplify the signal). |
