hello mam.......i want to know the application/role of a capacitor in a celling fan& tubelight.

i want to ask that "our household supply is 220V , somewhere in industries it is 440V......i also found out that somewhere from where high transmission line is going it is written 11KV, 33KV etc................these all are multiples of 11 " i want to ask that what is the reason behind it?

Challenge of the Week

Hello Friends,

Sorry for not being in touch for so long....i know exams are coming up for the present students...and they are too busy with their preparations....ALL THE VERY BEST to all of you....

Continuing our trend of mind boggling puzzles....i am shooting you here with a small question...lets see which one among us answers it first....

The Question is:

Put two charged (one positive and the other negative)conducting plates facing each other at a distance of 10 cm. Assume the charge in each plate is 1 Coulomb and each plate has dimensions of 5 cm by 5 cm. If you discharge this capacitor certain amount of energy is released (the spark).

If, before discharging the plates, you pull them apart to reach 15 more centimeters, the energy released when discharged will be smaller or bigger than in the first case? Explain.

Waiting for the answer.........

Take Care....

Hello Friends,

I guess this year is fully loaded with achievements, achievements and more achievements....we had not been able to come out of the happiness and celebrations for VI MANTRA 2008 that another PRIZE came in to our arms......The Prize this time is for a 10 minutes paper presentation in a contest called......

CONVERGING VECTORS
Inter- College Paper Presentation Competition
Held on 13th December 2008
Organized by ARYABHATTA SCIENCE FORUM,
Deen Dayal Upadhyaya College, University of Delhi.

The event had participation from a lot of colleges in Delhi University and people had great topics to present. The event also included great participation from our own college in the field of electronics. 5 different papers were selected for participation after final scrutiny among the entries from the electronics department in ANDC.....The event also had two other categories....Physics and Computer Science.....both categories involved overwhelming participation from ANDC as well as other colleges....

The great news is that in the category of Physics and Electronics....ANDC beat all the other participants and stood first among the others thus winning a cash prize of 1000/- each apart from the certificate of prize.

Our heroes from Electronics are ANMOL BAGGA and MIGMAR DOLMA.....from B.Sc.(H) Electronics-III.........Both of them as a team made a presentation on BIOMETRICS. However, the topic was presented by ANMOL BAGGA which fetched us the first prize.......

3 Cheers for ANMOL and MIGMAR........Hip Hip Hurray!!! Hip Hip Hurray!!! Hip Hip Hurray!!!

Well done guys....keep rocking........ELECTRONICS ANDC ROCKS!!!!!!

Great News!!!!!!!!

Acharya Narendra Dev College is proud of our students and teachers of Electronics who have won the third prize at the very prestigious National Instrument's paper contest VI Mantra 2008 in the student category.

The work reported in the paper 'Study of Hall Effect using LABVIEW' emanates from the project done with our B.Sc. (H) Electronics-III^rd year students - Anshul Vinay Parmar, Migmar Dolma and Rohit Gambhir - with Dr. Amit Garg, Ms. Reena Sharma and Mr. Vishal Dhingra in the Department of Electronics. It was a tough competition where 107 entries were shortlisted in the student category from submissions received from about 800 reputed Engineering colleges in India. We then went on to win the third prize which is an accomplishment since we were competing with best engineering colleges in the country.

The students were taken to Bangalore and provided accommodation in a five star hotel to attend the Prize distribution ceremony on NI Educators Day 2008 in Bangalore by the organisers. Besides, the students will get a chance to present this paper to Industry Experts at the 7^th National Conference on Virtual Instrumentation in Engineering Education 2008 to be held in New Delhi. As part of the prize, we have also received the Student Version of LabVIEW and certificates from National Instruments to all the authors. They have also won 1000 USD from National Instruments for Lab up-gradation. We can proudly announce that its only the second time in 6 years that any team from North India has won any prize at this prestigious event. The earlier winner from this region was in 2002 and he is now working with National Instruments.
