What are electronic devices?
Electronic devices are devices which involve the control of the flow of electrons by means of other electrons, rather than by mechanical means. A physical switch, consisting of a piece of metal which touches another piece of metal to pass along a flow of electrons is NOT an electronic device, but rather is an ELECTRICAL device. A TRANSISTOR, in which a small voltage controls a larger flow of electrons, IS an ELECTRONIC device. A vacuum tube is also an ELECTRONIC device, because a small voltage on the grid of the tube controlls a larger current of electicity through the tube.

All modern day computers are built using electronic or semiconductor processors and components, so these are electronic systems which of course need electrical power to operate but are not in general put under category of electrical devices..
Only because that is the best technology currentlyavailable to build them with. Many computers have beenproposed and/or designed and/or built with other technologies, afew of which are (with an example if possible): . mechanical - Babbage's Analytical Engine , designed butnever built and Zuse's… Z-2 . electromechanical - Aiken's Harvard Mark I and IBM's SSEC and Zuse's Z-3 . hydraulics/fluidics - proposed for use in high radiationenvironments (nuclear reactors, satellites, etc.), some prototypesbuilt in 1960s . optical - possible future replacement for electronics,prototypes still in development . holographic - still largely hypothetical proposals . quantum - very limited prototypes built but promises anunlimited increase in processing speed . etc. ( Full Answer )

clipper is an AC application of diode. The Clipper clipps off a portion of the input signal waveform without distorting the remaining part of the alternating waveform. We can use different type of alternating waveforms as input such as sinusoidal, Triangular, square etc. There are different types of… clippers e.g. series clipper, parallel clipper etc. but the method for solving all the type of circuits are same. So there is no need to remember the procedure for one particular clipper circuit. There are different types of clippers e.g. series clipper, parallel clipper etc. but the method for solving all the type of circuits are same. Now let us discuss the procedure with the help of a problem. Suppose we have given a clipper circuit shown below: Because clipper is an AC application of diode. So we apply an AC signal at the input Vi. Our aim is to find out the waveform of V o . The solution steps are: Step 1 : First of all analyze the circuit by bifurcating the input waveform in positive half cycle and negative half cycle. Step 1.1 : Positive half cycle : Positive half cycle is equivalent to a battery of positive polarity and variable potential. Step 1.2 : Negative half cycle : Negative half cycle is equivalent to a battery of negative polarity and variable potential. Step 2 : Now analyze the circuit with positive half cycle. The next step is to check the condition of diode i.e., whether the diode is forward bias or reverse bias. In the circuit shown above it is clear that the diode is forward bias and hence equivalent to short circuit (because it is ideal diode). Now analyze the variation of Vo. It is clear that And because V i varies sinusoidally, so V o also varies sinusoidally. Step 3 : Now analyze the circuit with negative half cycle The next step is to check the condition of diode i.e., whether the diode is forward bias or reverse bias. In the circuit shown above it is clear that the diode is reverse bias and hence equivalent to open circuit (because it is ideal diode). Now analyze the variation of Vo. It is clear that Step 4: Now combine these two waveform. ( Full Answer )

There are several ways to try and dry a wet device, like an iPod or cellphone. They work to differing degrees in different times, and can be used together or alone. . Place it in a warm, dry room for a few days, testing daily to see whether it has dried yet. . Turn a hair dryer to low and wave it… over the device from about a foot away for 20 to 30 minutes. Test it, and continue drying for another 20 to 30 minutes if necessary. . Place it in a cup of rice (rice absorbs water, but won't clog up the device). Another Answer . Using a hair dryer is a very bad idea: all it does is push the water further into the cracks and crevices of the device, making the problem worse. Rice also does not work, as it does not absorb moisture from the air, and it only absorbs a significant amount of water if the water is boiling. The only reason people say it works is that sometimes, if the device wasn't too wet to begin with, it just dries out by itself. It would have dried out without the bag of rice, but since it was in the bag of rice, people think it was the rice that dried it. Not so. The device just dried by itself. . By far the best way to dry out wet electronic devices is with silica packets. You know those little packets you find inside your new shoes, or in your medication bottle? They usually say "Silica - Do Not Eat?" These packets draw in and absorb moisture. They are put in shoes and medication bottles to keep humidity and moisture from ruining the product. Sometimes in medication bottles they come not in packets, but in little white plastic cylinders. . Every time you find a silica packet or plastic cylinder, save it. Put all of them in a sealed plastic bag, so they stay fresh and do not absorb moisture from the air. Next time one of your electronic devices gets wet, wrap it in a paper towel and seal it up in the bag with the silica packets. Wait 3 to 5 days. Your device should be good as new. . Several months ago I dropped my TV remote into a bucket of water. I didn't even notice at first, so the remote stayed submerged for nearly 10 minutes. After shaking the excess water out of it, I wrapped it in a paper towel and put it into a Ziploc bag full of silica packets and cylinders I had saved. Five days later I took it out, and it was good as new. It's still working perfectly, some 8 months later. ( Full Answer )

Remote controls very much an electronic device. The electronics read button pushes and convert them into streams of pulses. The pulses are sent to a light emitting diode (LED) where they are turned into light. Therefore the link between the remote control and the television is a purely optical one.
It depends on the amount of resistance, or load, the device is on the circuit. Do you have a particular device you're asking about?
Electronic devices works with electric current (AC / DC), some conductors are used to control current by amplifying, change in voltage etc. All eletronic devices have its own power supply system that regulates electric current. These power system uses transfermer with diode and capacitors in old… days but now transiter is used along with other as in smps. Main function of typical power suply system is to give electrical devices constant voltage/ current and save from sudden change in voltage. Sometime different part of electronic device requries different voltage electric current, which we have with power supply. Other systems of electronic devices are just controling/modifying current, frequency of electrical current, amplification etc. all this is done easily by semiconductor like transitor, diode etc. ( Full Answer )

One type of electronic control device is a hand held immobilizing device â¦ that is used by police departments to control uncooperative or dangerous subjects. It is operated by propelling two darts at a hostile subject. When the two darts â¦ strike the subject, so long as both [hooked barbs]… remain in contact with the subject's body and/or clothing, the officer can send an electrical charge through the wires. The officer can continue to send charges through the subject by depressing a buttonâ¦. The current generated by the [electronic control device] causes involuntary muscular contractions in the subject, which in turn usually causes thesubject to lose muscular control for a short period of time and to fall tothe ground. Because the â¦ subject loses muscular control, an officer can establish control over an uncooperative or dangerous subject without the need to resort to mace, batons, or personal combat techniques.
