1. why not solar energy is very much common in india inspite of 305 days are clear sun shine.<br />

2. i want to participate in Electrical seminar<br />

3. At 400Hz Transformer rating is 400KVA, what will be the KVA rating at 50Hz?

4. please give a tutorial on transformer winding and designing i.e turn ratio,current rating etc

5. If we took a cheap portable generator and remove the engine that drives it, attach it to bike pedals or turbine blades and run it on humanpower or steam, will it work just the same? Thank you.

6. I need some help to see if there is a solution that will involve not using a generator. Are there any batteries that would be capable of operating a table top food warmer with a 400 watt heat element and 100 watt bulb? If there are, what would be the max duration the warmer could reasonably function. The idea is to make a portable food cart bicycle. Most hot dog vendor bicycle carts use propane but will make food soggy. I just need a warming device for items like pizza or bread sticks, food you don’t want steamed. A generator would be too loud for a small bicycle food cart. Are there any batteries or innovative ideas that could work?

Thanks!

16. Hi,
I bought a mobile phone from USA a Sprint samsung galaxy s2 d 710, a CDMA phone, it means they have not a sim slot (they have only an SD memory card slot.). I found in the market a device comprising the sim card slot and the SD memory card slot together.
My question is: Can I remove the old device which has only SD memory card slot and replace it with the new one comprising the two slots and put it on the motherboard ? Can this new device work properly whithout problem ?
Best Regards
