Is a dynamic contrast ratio of 1000000 to 1 better than a static contrast ratio of 20000 to 1?

Contrast ratios on televisions screens get better and better with each model that comes out. Unfortunately, there are many ways of measuring contrast ratios and claims of ratios like 1,000,000:1 are using some very creative measurement techniques indeed.

Contrast ratios are affected by many factors including ambient light levels, image content, production techniques during editing and more. While a high contrast ratio suggests that you will see whiter whites and even blacker blacks, the numbers really don't mean a great deal compared to your own eyes. Before buying, make sure you look at televisions and decide for yourself just how white and how black the image gets. More importantly, look for detail in the very light and very dark parts of the image. Rich blacks with some detail in the darker areas is good and the same for very light detail. Your own viewing will give you a far better comparison between two screens than the numbers ever can.

How do you use a humidastat?

I believe that a humidastat is an exhust fan that is triggered on/off by the relative humidity of the enviorment where it is located.

Nomally these units simply vent heavy moist air out of the lowest point of a building. Heavy, cool, moist air will find its way to the lowest point of an enclosed structure, such as a basement.

This moist air is conducive to the growth of mold. If the moist air can be vented out of the lowest spaces of a structure, drier air from above will replace it.

A dehumidifier will dry the air in a basement, but it is power hungry machine, something that never stops in the humid days of summer.

It is the cool walls of a basement that creates an air flow, drawing down humid air, to the lowest point of a structure. If that air from the lowest point, can be pumped out, better air will replace it from above.

A simple 'muffin' fan will move enough air to do this job, it will run on less the 1/2 amp, kinda like a 60 watt bulb, compare that to the electric bill of a dehumidifier.

Basically, you need an air pickup at floor level and venting at ground level outside. A humidisat could turn this devise on an off, or you could simply run it on a timer in the summer time when there is a problem, or maybe just let it run in the most humid days of summer...

Why Qpsk?

QPSK is used in CDMA because it helps achieve higher data rates. It is much better than simple PSK.

What is the difference between thermocouple and RTD?

A thermocouple measures temperature difference between two points, producing a tiny voltage corresponding to the difference in temperature. To measure temperature with a thermocouple, you need to know the temperature of one junction and calculate the difference from the table or equation for the type of t/c used.

An RTD changes resistance in response to temperature--to measure temperature with an RTD you measure its resistance (usually by putting a known voltage across it and measuring the current).

How many years of college education do you need to become an electrical engineer?

The following is by and according to the U.S. Department of Labor and particular to the education and training required for a engineer.

Engineers typically enter the occupation with a bachelor's degree in an engineering specialty, but some basic research positions may require a graduate degree. Engineers offering their services directly to the public must be licensed. Continuing education to keep current with rapidly changing technology is important for engineers. Education and training. A bachelor's degree in engineering is required for almost all entry-level engineering jobs. College graduates with a degree in a natural science or mathematics occasionally may qualify for some engineering jobs, especially in specialties in high demand. Most engineering degrees are granted in electrical, electronics, mechanical, or civil engineering. However, engineers trained in one branch may work in related branches. For example, many aerospace engineers have training in mechanical engineering. This flexibility allows employers to meet staffing needs in new technologies and specialties in which engineers may be in short supply. It also allows engineers to shift to fields with better employment prospects or to those that more closely match their interests. Most engineering programs involve a concentration of study in an engineering specialty, along with courses in both mathematics and the physical and life sciences. Many programs also include courses in general engineering. A design course, sometimes accompanied by a computer or laboratory class or both, is part of the curriculum of most programs. General courses not directly related to engineering, such as those in the social sciences or humanities, are also often required. In addition to the standard engineering degree, many colleges offer 2-year or 4-year degree programs in engineering technology. These programs, which usually include various hands-on laboratory classes that focus on current issues in the application of engineering principles, prepare students for practical design and production work, rather than for jobs that require more theoretical and scientific knowledge. Graduates of 4-year technology programs may get jobs similar to those obtained by graduates with a bachelor's degree in engineering. Engineering technology graduates, however, are not qualified to register as professional engineers under the same terms as graduates with degrees in engineering. Some employers regard technology program graduates as having skills between those of a technician and an engineer. Graduate training is essential for engineering faculty positions and many research and development programs, but is not required for the majority of entry-level engineering jobs. Many experienced engineers obtain graduate degrees in engineering or business administration to learn new technology and broaden their education. Many high-level executives in government and industry began their careers as engineers. About 1,830 programs at colleges and universities offer bachelor's degrees in engineering that are accredited by the Accreditation Board for Engineering and Technology (ABET), Inc., and there are another 710 accredited programs in engineering technology. ABET accreditation is based on a program's faculty, curriculum, and facilities; the achievement of a program's students; program improvements; and institutional commitment to specific principles of quality and ethics. Although most institutions offer programs in the major branches of engineering, only a few offer programs in the smaller specialties. Also, programs of the same title may vary in content. For example, some programs emphasize industrial practices, preparing students for a job in industry, whereas others are more theoretical and are designed to prepare students for graduate work. Therefore, students should investigate curriculums and check accreditations carefully before selecting a college. Admissions requirements for undergraduate engineering schools include a solid background in mathematics (algebra, geometry, trigonometry, and calculus) and science (biology, chemistry, and physics), with courses in English, social studies, and humanities. Bachelor's degree programs in engineering typically are designed to last 4 years, but many students find that it takes between 4 and 5 years to complete their studies. In a typical 4-year college curriculum, the first 2 years are spent studying mathematics, basic sciences, introductory engineering, humanities, and social sciences. In the last 2 years, most courses are in engineering, usually with a concentration in one specialty. Some programs offer a general engineering curriculum; students then specialize on the job or in graduate school. Some engineering schools have agreements with 2-year colleges whereby the college provides the initial engineering education, and the engineering school automatically admits students for their last 2 years. In addition, a few engineering schools have arrangements that allow students who spend 3 years in a liberal arts college studying pre-engineering subjects and 2 years in an engineering school studying core subjects to receive a bachelor's degree from each school. Some colleges and universities offer 5-year master's degree programs. Some 5-year or even 6-year cooperative plans combine classroom study and practical work, permitting students to gain valuable experience and to finance part of their education. Licensure. All 50 States and the District of Columbia require licensure for engineers who offer their services directly to the public. Engineers who are licensed are called professional engineers (PE). This licensure generally requires a degree from an ABET-accredited engineering program, 4 years of relevant work experience, and successful completion of a State examination. Recent graduates can start the licensing process by taking the examination in two stages. The initial Fundamentals of Engineering (FE) examination can be taken upon graduation. Engineers who pass this examination commonly are called engineers in training (EIT) or engineer interns (EI). After acquiring suitable work experience, EITs can take the second examination, the Principles and Practice of Engineering exam. Several States have imposed mandatory continuing education requirements for relicensure. Most States recognize licensure from other States, provided that the manner in which the initial license was obtained meets or exceeds their own licensure requirements. Many civil, electrical, mechanical, and chemical engineers are licensed PEs. Independent of licensure, various certification programs are offered by professional organizations to demonstrate competency in specific fields of engineering. Other qualifications.Engineers should be creative, inquisitive, analytical, and detail oriented. They should be able to work as part of a team and to communicate well, both orally and in writing. Communication abilities are becoming increasingly important as engineers frequently interact with specialists in a wide range of fields outside engineering. Certification and advancement.Beginning engineering graduates usually work under the supervision of experienced engineers and, in large companies, also may receive formal classroom or seminar-type training. As new engineers gain knowledge and experience, they are assigned more difficult projects with greater independence to develop designs, solve problems, and make decisions. Engineers may advance to become technical specialists or to supervise a staff or team of engineers and technicians. Some may eventually become engineering managers or enter other managerial or sales jobs. In sales, an engineering background enables them to discuss a product's technical aspects and assist in product planning, installation, and use. (See the statements under management and business and financial operations occupations, and the statement on sales engineers elsewhere in the Handbook.) Numerous professional certifications for engineers exist and may be beneficial for advancement to senior technical or managerial positions. Many certification programs are offered by the professional societies listed as sources of additional information for engineering specialties at the end of this statement.

What does a microwave leak dector do?

It checks that no microwaves have escaped from the oven.

Microwaves are harmful to living flesh. Not only will it cook you, as it does in the oven, but even small doses can cause eye cataracts.

The door seal has a mesh, that will trap the microwave radiation. The mechanical size of the mesh is designed to interfere with the radio wave length.

The door seals can get damaged with use and as radio waves are invisible, no one would know there is a problem.

By moving a microwave leak detector around the door seal and cabinet, you can check to see that the oven is safe.

The device can also be used for radar systems, that use wave guides up to the scanner, to check joints.

Why is alternating current used for domestic purposes?

Alternating current is easier to distribute than direct current, because alternating current can be raised or lowered in voltage by a transformer. This allows very high voltages to be used in long distance transfer of electricity, which is then stepped down several times before being supplied to the end user. As the voltage is increased in a circuit, the current, as measured in amperes, decreases for a given load. This allows the use of lighter wire to transmit large amounts of electricity.

Vacuum is 1100 watts how many amps is that?

If running at 110V, that is 10Amps.

Wattage = Voltage x Current

Current = Wattage / Voltage - Neeraj Sharma

Why electricity is produced upto 6.6kv or 11 kv in power plant but our requirement is only 440 volt?

It is mainly for transportation, especially over longer distances, that higher voltages are used. At higher voltages, less current is required - and power losses are proportional to the square of the current.
