Can the use of a violet wand cause damage to other electronic equipment with in a home?

Being a device that discharges voltage (even a small amount of electon flow, commonly called amperage) can disrupt or damage electonics. Extent would depend on the amount of VA (voltamps) as well as the particular electronics in question (how well it is grounded, shielded, what sensitive components exposed and other variables). Even without direct current flow any electronic 'generator' creates EMF (electromagnetic force) which can affect (such as RF (radio frequency)) or any component within a certain area that is susceptible to EMF. All this said, with 'normal' usage (read: no direct contact or extreme close proximity) MOST (read: well designed and produced) electronics are not affected within a building (household). I wouldn't use one on myself if I had a pacemaker though (disclaimer: I am not a doctor or engineer). Always use common sense and care when using any electronic device that could potentially injure or damage!

How can you make an electronic device that will buzz only if you separate it from the base unit to a distance after 3 meters probably work using frequency?

To create a device such as this one would chose a freguency is of a clear band width (avoid the upper frequency FM range) and mke the transmitter sufficiently weak that the signal would practically fade out in 3 meters. It is also possible to check the signal strength on the receiving circuit though this is prbably more sophisticated then need be as if you sufficiently under power, via gues nd check you should obtain the desired range.

What are those packs found inside electronics boxes that warn Do Not Eat?

A chemical used to absorb moisture. It is silica gel. It absorbs moisture. The following is from a poison control site: ''Question'': What is harmful about silica gel? ''Answer'': Silica gel is not toxic to humans. There is a warning sign on the packaging because it is considered a choking hazard. If children accidentally ingest silica gel, gently wipe out their mouth and give them something to drink to take away the bad taste. It's called desiccant. Do not eat iPod Shuffle. (sorry, BS answer, I know, but couldn't resist) Actually, it's a desiccant of some sort. A desiccant absorbs moisture so that whatever it's packed with will have reduced exposure to said moisture, thus helping to keep metal from rusting, pills from ruining, and electronics from shorting out. (Wikipedia) A desiccant is a substance that adsorbs water. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture

Why would a car be completely dead with no lights electronics or ignition after it was just running fine?

The only thing that comes to mind in a situation where a car that was running a short time ago and now is COMPLETELY DEAD is a failure of the battery or the primary cables/connections. I'd begin by checking the cable connections at the ends on the battery. The ends at the battery are more prone to failure than the other ends, but check both ends of the cables starting at the battery side. One would be wise to do this with caution, or, if lacking sufficient expertise, with some help.

Are Passive reflectors used in both Active and passive Satellite system?

Yes. The most common antenna for satellite systems is the 'Dish'.
The dish is a parabolic , passive, reflector.
It merely reflects and concentrates the signal to the LNB receiver.
Transmission also works this way, bouncing the signal off the dish, to concentrate it in one direction, in a narrow beam.

Electronic Warfare Officer?

By becoming an electronic warfare officer, you will have an opportunity to be on the front lines of protecting our nation’s borders from the treats of high tech enemies. You will also be equipped with the skills necessary to recover intelligence from apprehended storage devices and perform analysis on equipment that has been used in electronic warfare. While this type of career can be extremely rewarding for the right candidate, being an electronic warfare officer is not for everyone. Here is what you need to know about the qualifications and general job duties of an electronic warfare officer.

In order to become an electronic warfare officer, you will need to acquire training and certification in all of the major aspect of network security and electronic criminal investigations. Most of today’s electronic warfare officers obtained their training as members of the United States Air Force. In addition to basic computer security training, electronic warfare officer are trained in the specifics of our enemies electronic systems, the principles of electronic warfare and various methods of using advanced electronics to assist military operations.

The general job duties of an electronic warfare officers can vary greatly depending on where you are assigned. One day, you may be monitoring the border between open and protected airspace, and your day will be spent at your desk simply ensuring that no borders are breached. The next day, you could be rushing to give pilots as much protection as possible as they enter enemy airspace by employing radar jamming equipment and various methods of ensuring that the mission is completed safely and without detection.

One of the key qualifications to remain an electronic warfare officer is to participate in ongoing training. There are new electronic defense systems and warfare methods being developed every year, and it is the responsibility of an electronic warfare officer to ensure that he has the proper skill set necessary to confront any and all threats. This training is funded by the military, and the Air Force will adjust your schedule to include your studies. As an electronic warfare officer, your ability to handle new and emerging threats will frequently be tested military drills of possible warfare scenarios.

How do you recognise read the values and identify polarity and any other orientation requirements for all electronic for all electronic components being used in the assemblies?

If there’s enough room on the capacitor, most manufacturers of electronics components print the capacitance directly on the capacitor along with other information such as the working voltage and perhaps the tolerance. However, small capacitors don’t have enough room for all that. Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps.

If you have a capacitor that has nothing other than a three-digit number printed on it, the third digit represents the number of zeros to add to the end of the first two digits. The resulting number is the capacitance in pF. For example, 101 represents 100 pF: the digits 10 followed by one additional zero.

If there are only two digits listed, the number is simply the capacitance in pF. Thus, the digits 22 indicate a 22 pF capacitor.

This shows how some common capacitor values are represented using this notation:

Marking Capacitance (pF) Capacitance (ìF)

101 100 pF 0.0001 ìF

221 220 pF 0.00022 ìF

471 470 pF 0.00047 ìF

102 1,000 pF 0.001 ìF

222 2,200 pF 0.0022 ìF

472 4,700 pF 0.0047 ìF

103 10,000 pF 0.01 ìF

223 22,000 pF 0.022 ìF

473 47,000 pF 0.047 ìF

104 100,000 pF 0.1 ìF

224 220,000 pF 0.22 ìF

474 470,000 pF 0.47 ìF

105 1,000,000 pF 1 ìF

225 2,200,000 pF 2.2 ìF

475 4,700,000 pF 4.7 ìF

You may also see a letter printed on the capacitor to indicate the tolerance. You can interpret the tolerance letter as follows:

Letter Tolerance

A ±0.05 pF

B ±0.1 pF

C ±0.25 pF

D ±0.5 pF

E ±0.5%

F ±1%

G ±2%

H ±3%

J ±5 %

K ±10%

L ±15%

M ±20%

N ±30%

P –0%, + 100%

S –20%, + 50%

W –0%, + 200%

X –20%, + 40%

Z –20%, + 80%

Notice that the tolerances for codes P through Z are a little odd. For codes P and W, the manufacturer promises that the capacitance will be no less than the stated value but may be as much as 100% or 200% over the stated value.

For codes S, X, and Z, the actual capacitance may be as much as 20% below the stated value or as much as 50%, 40%, or 80% over the stated value. For example, if the marking is 101P, the actual capacitance is no less than 100 pF but may be as much as 200 pF. If the marking is 101Z, the capacitance is between 80 pF and 180 pF.

Why do solar cells need to lower resistance in the electrical circuits that make up their electronic system?

Reducing the resistance of solar cells increases the output current. Although the voltage remains the same the current is effected due to internal resistance. A reduction in output current can result in lesser diminished functioning in household appliances.
