FAQs

1. What causes static electricity? 

Ans: Static electricity is caused by the transfer of electrons between materials through friction, contact, or induction.

2. How can static electricity be prevented? 

Ans: Static electricity can be prevented by grounding, maintaining proper humidity levels, and using conductive materials.

3. What are some common applications of static electricity? 

Ans: Common applications include photocopiers, air purifiers, and electrostatic painting.

4. Why does static electricity build up more in dry conditions? 

Ans: Dry conditions reduce the conductivity of air, making it harder for charges to dissipate and leading to more static buildup.

5. Is static electricity dangerous? 

Ans: While generally harmless, static electricity can pose risks in flammable environments and when handling sensitive electronic components. Proper safety measures should be taken to mitigate these risks.
