Understanding Static Electricity

The video explains static electricity, where charges build up but do not flow. It describes how clothes in a dryer become charged due to electron transfer between fabrics, leading to static cling. The video also covers electrical discharge, which occurs when built-up charges move suddenly, such as when touching a doorknob after walking on a carpet.

What is the primary reason clothes stick together in a dryer?

• The heat from the dryer

• The transfer of electrons between fabrics

• The type of detergent used

• The spinning motion of the dryer

What happens to your body when you walk across a carpet?

• You lose electrons and become positively charged

• You gain electrons and become negatively charged

• You remain electrically neutral

• You gain protons and become positively charged

Why do you feel a shock when touching a doorknob after walking on a carpet?

• Protons jump from your body to the doorknob

• Electrons jump from your body to the doorknob

• The doorknob is negatively charged

• The doorknob is positively charged

What is electrical discharge?

• The slow movement of charges

• The gradual build-up of static charges

• The sudden movement of built-up charges

• The continuous flow of current

Which of the following best describes the process of electrical discharge?

• A continuous flow of electrons

• A gradual build-up of static electricity

• A slow release of energy

• A sudden release of stored electrical energy
