Q

What are three ways to tell if static E. Is present

A
  1. It makes sparks and can shock you
  2. It makes a crackling sound
  3. It causes things to stick together

Q

What are the three everyday examples of where static E. occurs

A
  1. Dragging rubber-soled shoes can take electrons from the carpet creating a shock
  2. Clothing rubbing together in the dryer taking electrons, causing static cling (clothes sticking together)
  3. Electrons collect on TV producing static electricity

Q

What is the example (parts 1-4)

A

Rubbing the balloon steals electrons from your hair. The balloon has extra electrons and has a negative charge. Your hair has less electrons and has a positive charge. Opposites attract so the balloon will stick to something positive. If there are enough electrons, the will try and jump to the wall and make a spark
