Electrostatic energy on my cat?

Click For Summary
SUMMARY

The discussion centers on the electrostatic energy generated between a person's hands and a cat's fur during play. Participants conclude that the person likely acquires a negative charge due to the cat's sharp hairs donating electrons. A standard voltmeter is suggested for measuring voltage, although it is noted that typical voltmeters may not effectively measure such low voltages due to their electrical resistance discharging the body. Additionally, the limitations of voltmeters in determining the polarity of the charge are highlighted.

PREREQUISITES
  • Understanding of electrostatics and charge transfer
  • Familiarity with voltmeters and their operation
  • Knowledge of electron donation and acceptance in materials
  • Basic principles of measuring voltage
NEXT STEPS
  • Research how to use a high-impedance voltmeter for measuring electrostatic voltage
  • Learn about materials that generate static electricity, focusing on fur and skin interactions
  • Explore methods for safely measuring electrostatic charges
  • Investigate the principles of charge polarity and how to identify it
USEFUL FOR

This discussion is beneficial for pet owners, physics enthusiasts, and anyone interested in the principles of electrostatics and charge measurement.

When I play with my cat, there is some electrostatic energy generating between my hands and cat's fur, does anyone have any suggestions whether my body get positive charges after playing with my cat or negative charges?
Thanks in advance for any suggestions

Likely negatively charged. The sharp hairs of the cat are more likely to donate electrons to your hand.
 
A simple volt meter would tell you for sure.

This voltage from electrostatic energy is fairly difficult to measure on a volt meter. A normal voltmeter won't work: the electrical resistance of a normal voltmeter will discharge your body almost instantly.
Furthermore, on a volt meter, is there any feature to determine whether the charges are positive or negative? It seems to me that there is only one direction scale for voltage, and cannot tell whether the charges are positive or negative.

Does anyone have any suggestions on how to measure the voltage from electrostatic energy? in order to determine whether the charges are positive or negative?
Thanks everyone very much for any suggestions
