Why is it better for appliances to work from batteries?

Some appliances are better adapted to batteries based on portability. Batteries allow significant portability. Appliances that remain in place, like a refrigerator, would not need batteries.

Are 5mw green lasers legal in Ireland?

Sure it's legal! Everything is legal in Ireland!!!! XD ;)

Is FADEC used in the military?

The F-35 has it, but military pilots wouldn't want it. FADEC systems have no manual override; if the FADEC quits working, so does the engine. The Air Force uses digital engine controls on planes like the C-17 and C-130J, but they'd want to be able to override the system if necessary.

What does wifi only model mean?

If your electronic device is said to be "Wi-Fi only" model, this means that this particular device is only outfitted with a WLAN card that only allows you to connect to the Internet via "Wi-Fi hotspots" or "access points" as opposed to a 3G or 4G version that also has a WWAN card that will require you to sign up for a data plan with a mobile phone carrier.

Which College course will give you the best career opportunities?

Harvard Law School is the obvious answer, but if you want something that is useful, I would recommend electronics with a specialization in RF technology.

What over the ear headphones compare to the Sony MDR-XB500 that are around the same price and bass sound quality?

Skullcandy GI or skullcrushers are great if a little flimsy, bass and clarity being better in the GI, the hesh aren't that great for quality just loudness, or save a little and buy aviatiors as they will be on offer.

Why do guitar rockers choose tube amplifiers instead of transistor amplifiers?

A: TUBE AMPLIFIERS are operating at higher voltage which makes the dynamics of amplitudes more desirable. Other then that there is no other reason. tube amplifiers are bulky heat generating components efficiency poor and frequency limited.

Do the watts split if you connect more than one speaker to an amp channel?

First if you are talking about normal speaker (not subwoofer), I would not recomend doing that.

There is different ways to connect multiple speaker to one amplifier chanel.

You could wire it in serie or in parralel.

If your are talking about dual voice coil or more than 2 speaker, there is even more possibility to wire two or more speaker to one channel.

Now if you are talking about single voice coil subs, in a perfect situation, by wiring them in parralel, the wattage should not get lower but the impedence will be divided by the number of sub you hook up. You will need to make sure the amp can support a lower impedance.

What is the iPad categorized as?

The iPad is categorized as a Tablet Computer, other competitors in this category include the Galaxy Tab and Motorola XOOM. However, I prefer the iPad to it's competitors!

What is piozo electronic sensor?

A piezo electronic sensor is a device, usually some sort of crystal substance, that when bent, pressed, or twisted generates (usually small amounts of) electricity to attached wires. It is used in industry to control things and detect physical changes. A common use is in a microphone where the piezoelectric sensor (a crystal attached to wires) generates electric current from the vibrations it receives, feeding it to an amplifier.

Is thermocouple a temperature measuring device?

No, by itself a thermocouple can only measure temperature difference between two points (junctions) in a circuit. To use a thermocouple as a temperature sensor, you must know the temperature of one junction by some other means. Often an additional temperature sensor is used. However, in some applications temperature difference is enough. For example, in gas appliances a thermocouple detects presence of a flame because the flame is much hotter than room temperature-- you don't need to actually measure the flame temperature.

======================

Yes, it is. If you look up "thermocouple" in Wikipedia, you will find a very detailed

explanation of how and why they work.

What kind of backlighting do LCD HDTVs use?

The first main type of LCD illumination is called CCFL. CCFL uses strong bulbs - mainly florescent to light up the screen. Newer HDTVs have now switched to using LED technology, as LED lamps are smaller, less expensive to produce, maintain, & deliver better results than the CCFL illumination. There are three types of LED LCD back-lighting configuration for all modern HDTVs. The first type is called edge-lighting LED. Edge lighting uses LED bulbs built around the back edges of the screen. This configuration produces results worse than full LED illumination, and sometimes even worse than CCFL. It's used to make TVs very thin, mainly the ones that you can hang up on the wall. The second type is the fully lit LED LCD. This configuration (also known as Full Native LED LCD lighting) has the same round LED bulbs used in edge-lighting, except the entire back of the screen is populated, instead of just edges. This produces a much better picture than the edge lit displays, while the TV will not be as thin, and at a bit higher energy cost. The third type of LCD HDTV back-lighting configuration is the fully lit LED LCD with local dimming. This configuration supports the same fully populated LED illumination, except special TV software controls which bulbs are left on and off, all based entirely on the picture. Let's say there is a picture of a night in Paris with a lit up Eiffel Tower, local dimming option keeps the bulbs behind the black sky off, thus providing a darker black sky. The LED bulbs behind the light tower however will be lit up. Local dimming (also known as the dynamic dimming) is considered to be the best type of back-lighting because it constantly changes the lighting to serve each individual image displayed.

Why and how test equipment is calibrated in electionics?

Test equipment is calibrated against a standard of some sort that is stable. In many cases these standards are traceable to the standards at the National Institute of Standards and Technology (NIST) in Maryland.
