DOK Level 1: Recall

What is the principle reason that conductors can transfer electric charge easily?

• They have tightly bound electrons

• They have free electrons

• They are always positively charged

• They are made of metal

DOK Level 2: Skill/Concept

How does an insulator differ from a conductor in terms of electron mobility?

• Insulators have more free electrons than conductors

• Insulators allow electrons to move more freely than in conductors

• Insulators restrict the flow of electrons more than conductors

• There is no difference in electron mobility between insulators and conductors

DOK Level 2: Skill/Concept

What is the effect of grounding an object in the context of electrostatic discharge?

• It increases the electric charge

• It decreases the electric charge

• It provides a path for excess charge to flow safely to the Earth

• It isolates the object from its surroundings
