Static and Current Electricity

What happens when you touch a metal doorknob after rubbing your shoes on the carpet?

• The doorknob sends a burst of electric current into your body

• Millions of electrons go from your finger into the doorknob

• The doorknob sends millions of electrons into your finger

• our finger becomes negatively charged

Electrical charge built up on the surface of an object is called _________________.

• static electricity

• current electricity

• lightning

• electrons

Electrical charge built up on the surface of an object is called _________________.

• static electricity

• current electricity

• lightning

• electrons

Which of the following is caused by static electricity?

• a stove getting hot when it is turned on

• a magnet being attracted to a refrigerator

• lightning strike during a storm

• a light bulb coming on when a switch is turned on

What eventually happens to objects that are charged with static electricity?

• They destroy electrons forever

• They transfer electrons to air or as a spark to another object

• They transfer neutrons to the air

• They create more protons to become neutral
