Static Electricity Quiz

Why is static electricity classified as a charge rather than a current?

• It involves moving electrons

• It involves electrons that are not moving

• It involves protons that are moving

• It involves neutrons that are not moving

What happens to an object’s charge if electrons are removed from it?

• It becomes negatively charged

• It becomes positively charged

• It remains neutral

• It becomes bipolar

Why do static charges only accumulate on insulator materials?

• Insulators allow electrons to flow freely

• Insulators prevent electrons from flowing to a different location

• Insulators have no electrons

• Insulators attract protons
