Alkaline batteries use a different electroyte, and last five to eight times as long as long as zinc carbon cells

Wet cell batteries are rechargeable, but require a charger and can suffer from the memory effect. They also can contain harmful chemicals. Dry cell batteries are non-rechargeable but often last longer than one charged wet cell.

It is called the desiccant silica gel. It keeps out or prevents moisture to enter those shoe boxes. Moisture cause brittleness to shoes which makes it easily to be broken and it lessens the good quality of the shoes.

Suppose the amount of radiation that could be received from a microwave oven varies inversely as the square of the distance from it. How many feet away must you stand to reduce your potential radiation exposure to the amount you could receive standing 1 foot away?

When entering a freeway you should always look and make sure that there is an opening for you to enter. You should watch the surrounding traffic.

The Domain Name System is designed to translate names of any server anywhere in the world. A lab environment is often a secluded network segment that does not need access to any arbitrary server in the world. If required, a small number of host names can by typed into resolver configuration files so access to the full international DNS is not required.

nm is nano-meters. There will be a number preceding the nm. This number indicates how many nano-meters for a full wave length of the laser light.

Maximum power usage is defined by part 97.313 of the FCC rules and regulations governing Amateur Radio. For repeaters, maximum power is determined by the antenna's H.A.A.T. (height above average terrain). This can be calculated by using the FCC's online calculator at: http://transition.fcc.gov/mb/audio/bickel/haat_calculator.html

The very first piloted helicopter was invented by Paul Cornu in 1907, however, this design was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924. Another early helicopter that flew for a decent distance was the German Focke-Wulf Fw 61, invented by an unknown inventor. Igor Sikorsky is considered to be the "father" of helicopters not because he invented the first. He is called that because he invented the first successful helicopter, upon which further designs were based.One of aviation's greatest designers, Russian born Igor Sikorsky began work on helicopters as early as 1910.

for resistors and some other components capacitors inductors

because in ckt connection there r done some ohmic loss due to the connecting wires and other factor , so voltmeter reading is not equal to its rated reading.

and this also done due to different error like instrument error , measurement error etc...

The television has been available since the 1920s, while the first computer (in the modern sense of the word) was first created in the late 30s-early 40s. The computer, however, wasn't commercially available until 1975 when the Altair 8800 was released.

No they refer to two different features to the electronic device you are considering.. Intrinsically safe basically means your electronic devices circuit board are not going to blow up in certain atmospheres... ie- near other electronic equipment

they have expandable memory and they come in cards which just slot into a mounted part

LM317 is a variable-output voltage regulator. I would expect to find it in small home appliances with electronic controls, portable radios, car electronics, cell phone chargers, etc.

If you need to find the chip somewhere to do some repairs, you can probably ask a manufacturer to send you a (free) sample. Otherwise, you can buy small quantities online from places like digi-key.

A: This was asked before and the criteria remains the same a very hi reasoning quality to think concepts and troubleshooting along to know which book to look up for an answer. Nobody knows it all nobody can. To complex, to many fields

Just an addition to the above answer, I agree that choices are broad, but, then its a good thing also. By Identifying your interest area, you can be a master of that one specific field.

The initial step is to know the various specialization in the field of Electronics, having a superficial knowledge of them and then decide, what intrigues you most?.

I hope that part is already covered. Next step might be in the identification of the current direction of the research going on. For this, reading magazine articles are more useful over journals.

I hope this was helpful.

As far as I know, Cree has been in the LED chip manufacturing business for a lot longer than Osram and Philips and other lamp companies that have previously focused on older models like incandescents, halogens, and CFLs. As a result of this advanced engineering, LED bulbs from Cree, or smaller companies that use Cree chips such as LED Waves in NY or ElementaLED in CA, tend to be higher quality and last longer.
