heat based computer

there z upcming computer working on heat rather than on electricity...
i wanna know that z ths heat z that which dissipates across the components.....?

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....

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!!!!!!
