CIRCUITS & ELECTRICITY
A complete path for electricity.
Closed circuit
Height of a wave.
Amplitude
Materials that allow electricity to flow.
Conductors
Waves that can travel through empty space.
Electromagnetic waves
Heat transfer through direct contact.
Conduction
Energy source in a circuit.
Battery
Number of waves per second.
Frequency
Materials that block electricity.
Insulators
Color with longest wavelength.
Red
Heat transfer by moving fluids.
Convection
Flow of charged particles in a circuit.
Electric current
Higher pitch means this happens to frequency.
Increases
Why metals conduct electricity.
Free-moving electrons
Color with highest energy.
Violet
Heat transfer through waves.
Radiation
What happens if a circuit is open?
No current flows / bulb doesn’t light
Distance between wave crests.
Wavelength
Is wood a conductor or an insulator?
Insulator
Why does a phone receives signal in a vacuum?
EM waves travel without a medium
Heat always moves from ___ to ___.
Warm to cold
Why adding more bulbs reduces brightness.
Increases resistance / less energy per bulb
Wave property most related to energy.
Amplitude
Examples of good conductors.
Copper, steel, aluminum
Two properties that change with light color.
Frequency and wavelength
When objects reach the same temperature.
Thermal equilibrium
