Removing a static charge by providing a path to the ground is called __.

• electric transfer
• grounding
• switching
• seperation

Electrons move only within their atoms. The electrons react to electric fields, resulting in individual atoms having charged ends that are attract to charged objects

• friction

• conduction

• polarization

• induction
