Electricity
| Question | Answer |
|---|---|
| The flow of electrons | amperes |
| A circuit that has wires branching off to provide paths for the flow of electrons | parallel |
| A circuit that has a single path for electrons to flow | series |
| Anything that electricity can flow easily through | conductor |
| A product that doesn't let electrons flow easily | insulator |
| The electric charge at rest on an object | static electricity |
| The potential difference between two points in a circuit, measured in volts | voltage |
| The opposition to the flow of electricity | resistance |
| A series of wires and/or electrical devices that form a complete path through which electricity can flow. | closed circuit |
| Glass, foil and water would be considered these, in terms of thermal energy | conductors |
| Wood, foam and plastic would be considered these, in terms of thermal energy | insulators |
| The three things needed to complete and electric circuit | battery (energy source), wire, bulb (or other electrical appliance) |
| If resistance in a material increases, what happens to the current? | decreases |
| Which has more resistance; short thick pipe or a long, thin pipe? | long, thin pipe |
| Which color absorbs more heat; black or white? | black |
| If voltage in a material increases, what happens to the current? | increases |
| If the temperature of a material increases, what happens to the current flowing through it? | decreases |
