FAQs on Static Electricity Video Lecture - Science Class 8

1. What causes static electricity?
Ans. Static electricity is caused by the imbalance of positive and negative charges on an object. When certain materials rub against each other, electrons can be transferred, leading to the build-up of static electricity.
2. How can static electricity be discharged?
Ans. Static electricity can be discharged by touching a grounded object, such as a metal doorknob or a water pipe, to allow the excess charge to flow away.
3. Can static electricity be harmful to humans?
Ans. In most cases, static electricity is harmless to humans. However, in certain situations, such as when handling flammable liquids or gases, static electricity can pose a risk of causing a spark and igniting the material.
4. How can static electricity be prevented?
Ans. Static electricity can be prevented by using antistatic products, such as sprays or mats, wearing clothing made of natural fibers, and increasing the humidity in the air to reduce the build-up of static charges.
5. What are some common examples of static electricity in everyday life?
Ans. Some common examples of static electricity in everyday life include hair sticking to a balloon after rubbing it, clothes clinging together in the dryer, and getting a shock when touching a metal object after walking on a carpet.
