A material that allows electrons to flow freely from particle to particle

• Conductor

• Circuit

• Field

• Insulator

Consider the conduction charging shown. 

• Electrons move from the insulating stand into the sphere.
• Protons move from the bar into the sphere.
• Electrons move from the charged metal bar into the sphere.
• Protons move from the sphere into the negatively charged bar.
