Conductors, Insulators, and Static Electricity Quiz

Which of the following best explains why insulators prevent electron flow?

• Their electrons are tightly bound to atoms
• They contain no electrons
• Their electrons move freely between atoms
• They have more protons than electrons

What would happen if you tried to create an electrical circuit using only plastic components?

• The circuit wouldn't work because plastic is an insulator
• The circuit would work better than with metal
• The circuit would explode
• The plastic would melt instantly

Why are metals generally good conductors?

• Their electrons are loosely bound
• They have no electrons
• Their electrons are immobile
• They repel all electrons

What property makes copper a good choice for electrical wiring?

• Low resistance to electron flow
• High resistance to electron flow
• No electrons present
• Repels electricity

In what state does static electricity exist?

• As a buildup without current flow
• Only when moving
• Only in metals
• Only in liquids

What would happen if you replaced the metal wiring in a lamp with glass?

• The lamp wouldn't work
• The lamp would work better
• The lamp would be brighter
• The glass would conduct better than metal

Why is rubber used to insulate electrical wires?

• It prevents electron flow outside the wire
• It increases electron flow
• It makes electricity stronger
• It conducts electricity better

Which material would be best for making a static electricity demonstration?

• Wool fabric
• Copper wire
• Aluminum foil
• Iron nail

What happens to electrons in a conductor when voltage is applied?

• They flow easily through the material
• They remain completely still
• They disappear
• They become more tightly bound

Why doesn't static electricity flow like current electricity?

• It's a stationary charge buildup
• It moves too quickly
• It only exists in metals
• It has no electrons
