Static Electricity: Reduce Shock by Holding a Doorknob

Click For Summary
SUMMARY

The discussion centers on methods to reduce static electricity shock, specifically through the action of holding a doorknob. The consensus indicates that holding a doorknob (option B) effectively grounds the charge, minimizing the shock experienced when touching another person. Rubbing feet on the carpet (option D) does not eliminate the charge differential, thus still allowing for a shock. The inquiry also includes questions about the current flow between charged bodies, emphasizing the importance of grounding in static electricity scenarios.

PREREQUISITES
  • Understanding of static electricity principles
  • Knowledge of grounding techniques
  • Familiarity with electrical charge differentials
  • Basic concepts of current flow in electrical circuits
NEXT STEPS
  • Research grounding methods for static electricity reduction
  • Explore the physics of static charge and its effects
  • Learn about current flow calculations in electrical systems
  • Investigate materials that influence static charge accumulation
USEFUL FOR

This discussion is beneficial for individuals interested in physics, electrical engineering, and anyone seeking to understand and mitigate static electricity shocks in everyday situations.

You rub your feet on the carpet in your warm living room on a cold winter day. You know you have gained static electrical charge on your body. You decide to touch your sister to shock her. Your sister knows that in order to reduce the electrical shock she will feel when you touch her, she
(A)must stand very still
(B) hold on to a doorknob
(C)jump up and down at exactly 60 Hertz
(D)rub her feet on the carpet

I have narrowed this down to answers B and D. I am leaning toward answer B, because if the sister rubs her feet on the carpet, as in answer D, there still might be a charge differential between the two people and therefore there would still be a shock. I think, but am not sure, that B would "ground" the charge. Please help!

How much current would flow between two bodies charged to the same level?

How much current would flow through a body that joined a body charged to a high level and a body at ground potential?
