Static Electricity: Can Insulators be Earthed?

Click For Summary
SUMMARY

Insulators cannot be earthed due to their inherent inability to conduct electricity. The discussion clarifies that while insulators can hold static charges on their surfaces, this property does not allow them to be earthed like conductors. The distinction between charged conductors and insulators is crucial, as only conductors can be safely earthed using a conducting wire. This conclusion aligns with established principles in physics regarding static electricity and electrical conduction.

PREREQUISITES

Homework Statement



I was just wondering if someone could help explain this problem I've been having. A lot of textbooks I've been studying from are describing how two insulators can become charged, but then don't mention whether an insulator can be earthed - it only mentions "charged conductors" being earthed using a conducting wire. Any help would be appreciated as to whether insulators can be earthed or not - only conductors.


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
An insulator cannot be earthed because it is an insulator - it doesn't conduct electricity by definition.

An insulator can hold a static charge on it's surface but this is not to be confused with being conductive.
