Study Notes
Electricity and Seismology
- A lightning conductor is a device used to protect buildings from the danger of lightning.
- The process of transferring charges from a charged object to the earth is called earthing.
- An electroscope is a device used for detecting and determining the presence of electric charges using electrostatic attraction and repulsion.
Seismic Activity
- The sudden shaking and trembling of the earth is called an earthquake.
- Seismic or fault zones are areas of intense seismic activity where earthquakes are more likely to occur.
- The significance of seismic or fault zones lies in their potential to generate earthquakes.
Static Electricity
- Static electricity is the accumulation of electric charges on the surface of an object.
- The process involved in the creation of static electricity is the transfer of electrons between objects, resulting in an imbalance of electric charges.
- Electric discharge is the release of static electricity, often accompanied by a spark or flash of light.
Earthing and Lightning Conduction
- The main purpose of a lightning conductor is to redirect lightning strikes harmlessly into the ground, protecting buildings from damage.
- The process of earthing involves transferring electric charges from an object to the ground, neutralizing the charge.
Test your knowledge of physics concepts related to static electricity, seismic waves, earthing, lightning conductors, earthquakes, and the functioning of an electroscope.
