The correct answer is: B. Conductors
Conductors are materials that allow electricity to flow easily. They are made of atoms that have loosely held electrons. These electrons can move freely from atom to atom, carrying an electric current.
Insulators are materials that do not allow electricity to flow easily. They are made of atoms that have tightly held electrons. These electrons cannot move freely from atom to atom,
so they cannot carry an electric current.Electron flow is the movement of electrons through a conductor. It is what allows electricity to flow.
Stimulators are devices that produce a stimulus, such as a light or sound. They are not materials that allow electricity to flow.
Here are some examples of conductors:
- Metals, such as copper, silver, and gold
- Graphite
- Molten salts
Here are some examples of insulators:
- Plastics
- Rubber
- Glass
- Air
Here are some examples of stimulators:
- Light bulbs
- Speakers
- Microphones
- Vibrating motors
