Lightning conductor :
This is a simple device used to protect tall buildings from the
lightning.
It consists of a long thick copper rod passing through the building to ground. The lower end of the rod is connected to a copper plate buried deeply into the ground. A metal plate with number of spikes is connected to the top end of the copper rod and kept at the top of the building.
When a negatively charged cloud passes over the building, positive charge will be induced on the pointed conductor. The positively charged sharp points will ionize the air in the vicinity. This will partly neutralize the negative charge of the cloud, thereby lowering the potential of the cloud. The negative charges that are attracted to the
conductor travels down to the earth. Thereby preventing the lightning stroke from the damage of the building.
Prayaag Eduserv focuses to bring out educational digital contents in audio visual e-learning format, which is easy to understand and help the student remember as and when required. It relieves the student from cramming, memorizing the school text books.We thereby meet the unmet need of learning the school curriculum in multimedia format which makes the student motivated to learn deeper with ease, instead of learn by route.
Our ultimate vision is to trigger creative imagination of the students to learn the content with enthusiasm. With the above mission in mind, we ventured to create Audio Visual Content for Tamilnadu State Board +2 Science & Mathematics. Each subject is given with animations, graphics, images, videos to help the students understand in a simple way. Number of academic experts who are leaders in the respective subjects worked hours &hours with visual communication technology experts to bring about an excellent collaborativeproject of educational ecosystem to achieve the best exam results. The DVDs are easy to use and hence the students enjoy learning.
We have included Multiple Choice Questions (MCQ), Frequently Asked Questions (FAQ) plus solved Board Exam papers.
To start with, we brought out Physics, Chemistry, Biology &Maths for +2 Tamilnadu State Board Syllabus in English. Soon we will have Physics, Chemistry Biology &Maths for +2 TN State Board Tamil medium students, as well.
This long journey only just started. Our management is not only focused on the exam results but also on mind development of the students. As we progress we will bring out educational DVD's for +1 and 10th standard students for Tamilnadu State Board.The passion to benefit all the stakeholders including parents, students and teachers, driven us to center our attention on the art and the science of delivering client-delight.
The unique feature of our DVD content is our natural,easy to understand voiceover which reflects closely the contents as mentioned in the respective text books and also explains the visual images very clearly.
It is our endeavor and hope that all our efforts will help the students achieve their Educational Goal and also build job oriented career by preparing the students for engineering and other professional courses.
