Question:
Insulators can be charged by which of the following process?
Insulators can be charged by which of the following process?
Show Hint
Conductors are often charged by induction, but insulators are typically charged by friction due to localized electron movement.
Updated On: Apr 23, 2025
- Induction
- Diverging
- Friction
- Heating
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Insulators do not allow free movement of charges. They can be charged by rubbing or friction, which transfers electrons from one object to another. This method is called charging by friction and is commonly demonstrated using materials like glass and silk.
