How has technology changed science?
It has made it easier to do discoveries. For example, microscopes have made it easier to see small particles and telescopes make it possible to see other planets.It also takes much more precise and accurate measurements.
What happens when a capacitor connected across a battery for a long time?
For a long time, The capacitor will be charged to the voltage of the DC battery, the positive side of the capacitor touching the positive terminal of the battery. Not much DC current will conduct, except for some tiny leakage current due to imperfection of the cap. The battery will be drained eventually.
System applications for the 741 op amp?
short circuit protection excellent temperature stability internal frequency compensation high input voltage range null of offset if you want what they do the look it up on google THERE MANY PLANE ROUND HAT HAVE GOBS OF 741 AMPLIFIERS THEY WERE USED IN A SYSTEM AS FUNCTION GENERATOR MULTIPLIERS AND SO FORTH. But that is ancient history. Of the 1960-70 . It was very common them for cheap not so reliable performance amplifier.

Does the Slide Text Messenger from Limited Too come with two electronics?
Well stated by the answer on the website and having one myself, it does.
:P :P
Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel.
ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
What happens to a 220v 50hz stereo amplifier when connected to a 220v 60hz supply?
Nothing happens. The stereo has a transformer that converts the power to DC, and 50 or 60 Hz input makes no difference.
What in soda makes the corrosion on a battery dissolve?
My thoughts are that it's the citric acid used in sodas today. Not sure, but I don't think that sugars and colorings have much to do with it.
Use BAKING SODA not a soft drink!

Is performance of dry cell battery is better over wet cell battery?
yes, it is much better!!!:)
Performance is very subjective. For very high current useage, many wet cells perform better.
Are modern gel automotive batteries considered to be dry?
How does a switch in an electric iron turn off by itself?
Many irons have a built in timer such that it powers off if no input is received after some time has passed.
How much actual power does a 1KA transformer provide?
The kVA represents the power-handling capability of the transformer.So, if you were using a 1 kVA transformer at 110 volts, you could roughly estimate the maximum output to be 9 amps.
Which color printers are the most economical?
The cost of ink is the greatest expense when it comes to using printers. Many printers--especially inkjets--are priced very low, but you may find that replacing the ink cartridges costs as much as the printer itself. In addition, many printers are not built for heavy use over a period of time. You may spend money on new cartridges only to find that your printer has reached the end of its useful life. You can often save by buying ink from alternative sources or by refilling your cartridges. However, many printers will not work with refilled cartridges or with anything other than the brand's own cartridges. Some will work for a while with alternative cartridges or refilled cartridges and then suddenly quit. You want a printer that will meet your needs in terms of quality and amount of use, but will still use ink that is affordable. Keep in mind, however, that it is not just the price of the cartridge itself but the amount of ink it contains. Some may be cheap, but hold only a fraction of the ink that another cartridge provides. Here are a few links to information that may help in finding a printer that works for you: http://www.asapinkjets.com/article-Most-Economical-Inkjet-Printer.html http://answers.yahoo.com/question/index?qid=20060908115358AAouuoM http://www.techimo.com/forum/general-tech-discussion/30598-most-economical-printer.html http://web.consumerreports.org/test/Printers/?EXTKEY=SG72E00&CMP=KNC-CROELECG&HBX_OU=50&HBX_PK=printers Note: This is a JOIN page.

How do you fix an electric lighter's spark?
Either
A:Replace the button-spark module (these ogenerally occur in only one of two basic types) Just get another similar lighter and strip away all the plastic bits until you have the very basic spark-button module.
B: Modules often die from two common causes 1.Spring or 2.Electrical connection these things are replaced/fixed in the usual fashion.
And if you are REALLY desperate you could try re-winding the coil/brush system having tried all of the above first
