Q:How come water shorts things out?
Water is actually a pretty good insulator. The water molecules themselves don't conduct electricity very well at all. Water is conductive when there are substances dissolved in the water which dissociate into ions. It's the ions which actually do the conducting. If you placed pure water on electrical equipment, you would get wet electronic equipment, with little chance for shorting out. It would actually depend on the voltages in the electron equipment. But keep in mind that pure what does contain some ions. First there is the autoionization of water to make H+ and OH-. Secondly pure water has a pH of around 5.5 to 6 due to the absorption of CO2 from the air. This will result in H+ and HCO3- ions. So pure water is not ion-free and will conduct electricity if the voltage is high enough.
Q:In view of the EMP technology that some countries have, why can't we harden electrical lines and equipment?
military equipment is hardened against EMP. and if that fails we have backups. such as field phones (thats were i cringe) as for the civilan side of things, its not really worth it. one of the First known EMPs was created using Nuclear arms which you have other problems then your electronics being blown out. and with advances in weapons technology and the ability to create EMPs with out Nukes its to exspensive to try to harden everything. also the technology required as far as i know is pretty advanced it be hard to make without a industrailized economy as for the goverment not protecting us against EMPs thats up to the private industries who are suppling the electronics your using.
Q:A huge power surge destroyed all my electrical appliances. Who is to blame?
Wow, okorder
Q:which of the following electrical equipment cannot convert a.c into d.c?
diode, true converter: vague term that can mean anything. AC-DC converter, DC-AC converter, voltage converter, frequency converter, etc. transformer, false mercury-arc rectifier, true But note that common use of the word transformer is as a power supply that generates DC from AC, so in that sense true could apply here. .
Q:Any problem if I buy a flat above the building equipment room (with big electrical/electric devices)?
Depends on the devices, I lived below a cell tower (literally 1m over head, installed on the top of my building). After doing as much research as I could on it, I found that no one really knows for certain the effects of radio waves on humans. If your major concern is just large voltage electricals, the greatest risks are fire, a small magnetic field might interfere with your devices occasionally, and constant low hum.
Q:Can I learn Electrical Engineering casually?
You can gain some general knowledge in electricity, but electrical engineering, no way.

Q:How Does the electrical current in our brain work. Where is it produced, what is it, why do we have it, etc?
the electrical current travels through neurons, brain cell, that never reproduce, ever. you are born with them. as to how to prove it. well the pulses are really fast, literally faster than a single thought or movement. but ever notice how you could reach for something with your hand and then move forward with your feet. that is your brain saying oh, okay I am too far, better take a step so I can reach. but the first wave was just the hand and the second wave was the feet. but both major waves took hundreds of smaller waves to communicate to get all the muscles moving your heart beating to make you move.
Q:Can we use land line phone to control houshold electrical equipments. Is the techonology available?
The answer is a qualified yes. You can connect your lights and appliances to X10-based switches and dimmers, and use the X10 Telephone Responder to control them remotely by phone. This will not allow you to turn on a microwave, because microwaves require their buttons to be pushed. But you could control lights, appliances and HVAC remotely with the right X10 receivers connected. See the links below for some phone-based controllers.
Q:Hi all , I'm creating an Inventory system .?
You need multiple tables. Using int() auto_increment primary keys for linking each section of data you want something like : stock_codes ( id int(6) primary key auto_increment, stock_code varchar(45) unique key, stock_description varchar(45), stock_qty int(6), suppler_id int(6) ) stock_movement ( id int(6) primary key auto_increment, in_date date, out_date date, moved_qty int(6), stock_id int(6), ) It helps to have tables of suppliers details, client details, sales person details, department details etc. If items have possible alternative suppliers you dump the supplier_id from the stock codes and use a link table for the stock id and supplier id to identify each inward transaction. Add tables for any additional information using links from the other tables to co-ordinate the data.
