SUMMARY

Static electricity voltages can exceed 20 million volts, particularly when generated by devices such as Van de Graaff generators. While rubbing a nonconductive material can create static charges of approximately 20,000 volts, the danger lies in the current, which is typically low and not lethal. Understanding electrostatic discharge (ESD) safety is crucial for handling sensitive electronic components, as even low current can cause damage to devices.

PREREQUISITES
  • Basic understanding of electrostatics
  • Knowledge of electrostatic discharge (ESD) principles
  • Familiarity with Van de Graaff generators
  • Awareness of safety protocols for handling electronic components
NEXT STEPS
  • Research the principles of electrostatic discharge (ESD) safety
  • Explore the operation and applications of Van de Graaff generators
  • Learn about the effects of static electricity on electronic components
  • Investigate methods for preventing ESD in electronic environments
USEFUL FOR

Electronics engineers, technicians, and anyone involved in the design or maintenance of electronic devices, particularly those concerned with ESD safety and static electricity management.

i heard that when we rub a finger on a nonconducting material 20000v gets generated,we don't get electrocuted because of low current.is that true?...really 20k?..
i got a earful when i touched a smd ic from my professor,thats why i had this doubt...so any help please??

It's a little more complicated than that. You can build up a static charge on your body equal to thousands of volts depending on the conditions you're in. See the following PDF for some basic ESD safety. I found this online by searching for "static discharge", so there is a wealth of info out there if you want to look it up.
