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.
