Static Electricity: Can You Still Get a Shock Off the Ground?

Click For Summary

Discussion Overview

The discussion revolves around the phenomenon of static electricity and whether two individuals, both carrying an electrostatic charge and suspended off the ground, can experience a shock when they touch each other. The scope includes conceptual exploration of electrostatic discharge and the conditions under which it occurs.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Person A questions if two individuals off the ground would still experience a shock upon contact.
  • Some participants suggest that being off the ground does not prevent a shock, as long as a charge difference exists between the two individuals.
  • One participant proposes that the charge from Person A would distribute between both individuals, likening it to discharging a capacitor, and notes that the peak current may be less than if they were grounded.
  • Another participant reiterates that grounding is not necessary for a shock to occur, emphasizing the importance of the charge difference.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of grounding for a shock to occur, with some asserting that it is not required while others explore the implications of being off the ground. The discussion remains unresolved regarding the specifics of charge distribution and peak current in this scenario.

Contextual Notes

Limitations include assumptions about the nature of the charges, the specifics of the environment, and the definitions of grounding and discharge. The mathematical implications of charge distribution and current flow are not fully explored.

A (possibly stupid) static electricity question:

Person A is carrying an electrostatic charge. They touch person B, both get a shock.

If both persons were off the ground(eg hanging from ropes) ...would they still get a shock?

Why wouldn't they?
 
Because neither are earthed?
 
The difference will be that A won't get completely discharged but its charge will be distributed over the two persons. Like discharging a capacitor on another one.
The peak current may be less than in the other case.

they don't have to be
as long as a charge difference exists between them, there will be a transfer of charge
