Christopher latham sholes called his keyboard a QWERTY keyboard because it is the 6 letters on the third row of the keyboard

How do you pronounce the stress symbol in the stress and strain formula?

Different symbols are used but if you are referring to the greek symbol "σ", it is pronounced "sigma" (like stigma without the t).

The cost of running a desktop computer for one day in New Jersey depends on when it is turned on and off. The cost is usually about 10 dollars.

What was first method of recording television programmes?

It was called Cinescope. They put a cine camera in front of a TV monitor and filmed it! Perhaps kinescope is a preferred spelling. See: http://www.museum.tv/archives/etv/K/htmlK/kinescope/kinescope.htm

How electricity flows?

Electricity flows through wires. Negatively charged atoms will jump to positively charged atoms. They all jump really fast and it causes flow.

Electricity flows only in

A. An open circuit.

B. A closed circuit.

C. A magnet

D. An incomplete circuit

Will a bad capacitor shut down and restart after a few minutes?

The failure mode of a capacitor depends to some extent on it's construction. Ceramic capacitors can crack and go open circuit whereas large electrolytic capacitors can gradually fall in capacitance as they age and exhibit an increase in leakage current or they can fail suddenly and short circuit - particularly if they have been stressed by a higher working voltage than they are designed for. Tantalum bead capacitors in particular had a reputation for shorting out. In some circumstances, the rush of current can remove the short circuit making it appear to be OK. Damage such as this will be cumulative and the capacitor may exhibit warning signs such as fluctuations in capacitance and leakage current prior to breakdown but in most cases once a capacitor fails, it fails permanently and suddenly and should be replaced. Most things cannot be fixed by "turning them off and then on again" - in fact this is the kind of thing which is most likely to stress components and the most likely time for them to fail.

What is function of closed-core transformer?

Closed-core and shell-core transformer (1885) The development of the electrical industry was hindered by the fact that the dynamo could only supply electricity trouble-free to short distances; to longer distances a large portion of electric energy got "lost" through overheated cables. The electrical engineers of that period were well aware that cheap electrical transmission could only be achieved by increasing the voltage. However, the experiments with DC (direct current) constantly ended in failure. Between 1884 and 1885 three engineers at the Ganz factory, Ottó Titusz Bláthy, Miksa Déri and Károly Zipernowsky developed a new current distribution system based on the use of the induction apparatus called transformer. Their joint patent described a transformer with no poles and comprised two versions of it, the "closed-core transformer" and the "shell-core transformer." In the closed-core transformer the iron core is a closed ring around which the two coils are arranged uniformly. In the shell type transformer, the copper induction cables are passed through the core. The core consists of iron cables or plates. Based on this invention, it became possible to provide economical and cheap lighting for industry and households.

Where can you buy a resistor?

Your local Radio Shack can offer you a small selection of resisters. Newark Electronics has a very large selection of resisters and other electronic components that you can order. Do a web search on it for more information. Various electrical repair shops can sometimes help you get what you need.

What is the volt input for ac power adapter if a unit takes 6 D Cell batteries?

A D-cell delivers around 1.5 Volt per piece. NORMALLY (but not always!) six D-cell are joined in series to make 6 x 1.5 = 9 Volts.

Only in cases where a high current is needed there may be a facility to have 2x 3 serie cells in two branches parallel thus making it 4.5 Volts.

It is quite safe to assume you will need a 9 Volt AC-powered adapter for this equipment, exceptions observed.

With kind regards,

Palm treo hot sync just starts with no cable in it?

the treos will do this when the port has liquid damage, if they are dirty, or if they have corrosion... try cleaning the port with Isopropyl alcohol and see if you can clean it up enough to stop hot syncing itself

Can you find part number 41TYZ-B synchronous motor?

Sounds like you already have the part number. If you're trying to find one, try using Google.com and just type in that number in the search window. It may come up. That's where I usually start when looking for replacement parts.
