Electrical Engineering

Transformers is about the auto-bots landing on Earth searching for a magic cube. The yellow car (bumble bee) finds a boy who has the cube. Then the decepticons come for it and battle for it and at the end of the movie the transformers kick the decepticons butt's.

2. Imagine a Web server that maintains a table in which client IP addresses are mapped to the most recently accessed Web pages. When a client connects to the server, the server looks up the client in its table, and if found, returns the registered page. Is this server stateful or stateless?

Yes, but the ratio of P and Q should be kept equal.

the matched load is aresistive load which at (Q=0)which generated from the generator mesur the load at( Ql=Qc)and at it we get high efficancy as losses of T.L P1=mesured P2=(3^.5) V2I2cos fai delta p=p1-p2 eff=p2/p1*100>>>>>>high

Electrical engineering is low voltage, logic circuits, communications etc. Power engineering is electrical transmission and the like.

You want EE.

Any electrical load on the engine from accessories such as heater motor, radiator fan and A/C controls are detected with the help of an electronic load detector. The additional electric load is compensated for with the help of ELD's input by ECU.

A varistor is a "variable resistor". When its value changes it then changes the amount of electricity it drops. Some of the energy goes to do the job; some of the energy is "dumped" out as heat. How about this: the volume control on your radio is a varistor. A dimmer switch on your living room lights is a varistor.

A The term signify a range of frequency that are either excluded or included as a pass or no pass situation. The frequency are not set to a specific range it just depends when designing what is to be included or excluded for a particular circuit.

Electrolytic capacitors are used for power filter, decoupling, signal coupling and time constant setting, DC blocking, etc.

Polarized electrolytic capacitors usually play a role in power supply circuits or intermediate frequency and low frequency circuits for power supply filtering, decoupling, signal coupling, time constant setting, and DC blocking. Generally electrolytic capacitors cannot be used in AC power circuits. When used as filter capacitors in DC power circuits, its anode (positive) should be connected to the positive terminal of the power supply voltage, and the cathode (negative) should be connected to the negative terminal of the power supply voltage. Otherwise it will damage the capacitor.

As a senior female electrical engineering student - the only one in a class of 30, I've thought quite alot about why I'm still taking engineering, and why there aren't more females like me doing what I'm doing.

Engineering is logical. It's about definite results and profit. It's about getting "the right answer" to the question, because if a gadget doesn't work, it doesn't work. There isn't any ambiguousness to it like in the social world. In addition, it's not an absolute requirement in engineering to have verbal and social skills.

For women who aren't that comfortable socially, have a good aptitude in science in math, and either don't mind or are almost unaware that they the minority, engineering can be a perfect fit.

But there aren't too many women like that. And the ones who are, tend to take things like medicine and biology because they appear to help humanity more directly than engineering.

I don't know many women who grew up taking apart televisions and making hot wheels go "vroom, vroom", around the carpet. Even if a woman does choose engineering as a career, she is going up against men with whom engineering is alot like breathing, the interest has been there since they started crawling. With women, interest in engineering as a career is more likely to come in secondary school or beyond - because they excel in academics. And those women, like myself, have alot to catch up on.

Of course, I'm not saying that women don't have the aptitude for engineering, it's just that engineering is portrayed as cold and hard and efficient, and although women in general may appreciate these things, the average woman would rather be in a major that is more social, requires emotional intelligence, and clearly has a positive impact on society.

Potential free contacts (also called "dry contacts") are simply contacts which are physically operated with the main device, but not electrically connected to it. For example a motor contactor often has auxiliary contacts that are operated by the main coil and open and close at the same time as the main contacts but are not used for control of the motor starter. If they are connected to an outside circuit to indicate the status of the starter without being powered by the motor supply they would be considered potential free contacts.

These type also called Signal-Contacts.

In case of relays and switches if the common/pole is connected internally to a given potential like a 110V phase etc., the contact is not POTENTIAL FREE but if both the common and the normall open (and at time also the normally closed) contacts are presented to the user for connecting in his system as he pleases,the contact is said to be "potential-free".

A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave.

The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ).

The "opposite" concept is the narrow-band or tuned amplifier.

There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor.

depending on the amount of the load of transformer as well as the power factor of it, there is a transformer specific voltage drop at its terminals, due to the internal impedances. The on-load tap changer can / will be used to compensate this voltage drop or rise.

these are essential for circuits which are current sensitive, it regulates the amount of current which serves as protection for circuits. it is commonly used in Laser diode applications.
