Do electronic drums sets need amplifiers?
yeah you do. i haven't seen any that you don't. but i could be wrong
Current as a transfer of (+) charge so thats its direction of flow is opposite to that of electrons which are (-) charged
Transistor
FOR THE TEACHERS
You can't make the students learn better by changing the answer to the wrong one.
The humanity is positively progressing because the internet allows people to share the knowledge much faster.
By changing the answer to the wrong one you will only succeed in producing more Ds
Progress is= to knowledge share, do not slow it down!!!

Who sings the background song Yeah in Love Again in the WalMart electronics commercial?
The Scarlet Dukes perform "In Love Again" in the Walmart commercial. It's from their CD "Rogue Escapdes". more info here: http://prefabgroup.com/news.shtml
These are lights put on bridges, towers, buildings, buoys among many other things. They are used as a safety marker indicating there is an object attached to it or nearby.
Start with a basic high school physics course to get the theory. Continue with a basic electronics course and acquire some soldering skills.
Once you learn enough not to accidentally kill yourself you will also know enough to build a stun gun.
What are the measurement system stages of audio speaker?
Well audio speakers aremeasured in a few ways but i will explain a few. All speakers are measured in inches or millimeters according to the side, this measurement measure through the center. The frequency is measured in hertz. Then they are all measured in Watts.
What is the current spot price for solar grade polysilicon?
The numbers you've been viewing are for common "metallurgical grade" silicon, which must be highly refined - from native "two nines" - 99% pure - of purity to somewhere north of "six nines" - 99.9999% pure - of purity for use in photovoltaic - or "PV" - (solar) applications. For electronics applications, it's nine to eleven nines. PV benefits from trickle-down of advances in refinement of electronics-grade production, with the result that the best - and best-performing - PV grades are pushing 8 nines. Even at 6 nines, spot price has been hovering at $400 to $500/kg for well over a year.
If you're interested, metallurgical grade ("MG Silicon") is produced in reducing furnaces from common quartz sand - the stuff dirt's made of. At very high temperature and in the absence of oxygen, the silicon dioxide sand (silica sand, one of the most abundant minerals on earth) gives up its oxygen and leaves behind 99+% pure silicon - a gray metal which is granulated by crushers in preparation for sale.
For electronic applications, including those for PV, the MG Silicon is reduced (usually) with hydrogen and chlorine so as to yield gases which may be chemically refined to varying levels of purity. The resultant compounds are further processed to yield various forms of solid pure silicon, including Solar and Electronics grades.
The multi-tiered refining processes are extremely expensive to operate, so that the cost of refined silicon is several times that of MG Silicon. Long-term, large-quantity contract prices are frequently in the range of 50% of spot price level.

A demarc or DMARC is a point where the wiring of the telephone company meets up with the customer wiring. It is basically a dividing line between the outside and inside of the structure.
Basically, an electronic wallet is an encrypted storage device that holds credit card and other financial information that can be used to complete electronic transactions without re-entering the stored data at the time of the transaction.
What is meant by control electronics?
Control electronics are devices like remote controls. Control electronics are used to control other electronic devices
== == Wireless Indoor / Outdoor Sensor Highly Versatile !
The DA48/RC8360 & DA49/RC2260 Wireless Door Chime is battery powered and does not require electrical wiring. The DA48/RC8360 & DA49/RC2260 Wireless Door Chime works with a battery operated sensor at the door, whenever the door is opened it transmits a signal to a ac plug in remote receiver, within 150' feet of the door, to a receiver in a different location, thus announcing entry to your premises. The DA48 & DA49 Wireless Door Chime can only be used with a closed door. If your door sensor will be exposed to the elements then order the DA49, if the door sensor will not be exposed to the elements then order the DA48.
the property have a lot of benifit:
* Not recommended for metal doors - the DA50L is recommended for metal doors
* You can set different transmitters to play different sounds for different doors
* Remote Receiver with Volume Control, operates on 110 V, plugs into a wall outlet anywhere up to 150 feet of the transmitter
* Wireless - Simple Installation and Magnetically Tripped Sensor
* Battery Powered - 6V - Alkaline (PX28A/RC2095)
* No Reflectors,no Light Beams,no False Alerts
* 32 Frequency Codes, reduces interference and 150' Range
* Thirteen sound options set at button: These high quality sounds and options are only available on selected models of Carlon Chimes.

What can cause multiple electrical problems?
Answer
It could be many things. Grounds, power lines, computer (in newer cars), battery, alternator. Repost with some specifics. Good luck. Answer I need some more info. Typically Bad Ground, or Water intrusion on BCM (Body Control Module) If the CAR is a GM it is more than likely an interior BCM. That is not even the end of it, i could keep going on and on.

When did electronics get invented?
The word electronics began to be used in the 1940s In the late 1950s the term electronic engineering started to emerge.
How long will it take to become an electronic technician in a college or technical school?
I think you should complete a diploma course to become a technician by any recognized institute of your respective country. And it should be affiliated by your country's education system. also you can become technician by doing any part time course in electronics but first one is preferred.
Do people in Africa have computers?
No. Only monkey tubes exist in Africa: you pull the monkey's tail and it positions itself as a binary 1, and you bop it on the head and it positions itself as binary 0. Usually getting all the monkeys in row to participate in the binary sequence is quite challenging - I recommend bananas laced with Valium.
In simple terms, computer is something which can compute, and you need to have electronic devices for this purpose which can do very fast and efficient calculations . Apart from computing, where will your data lie after computaion, it has be to be stored somewhere and this is where electronic memories come into play. So, it is difficult to imagine a computer without electronics.
How much electronic waste is discarded each year around the World?
I'm not sure about the numbers, but what I can say for sure is that many companies started to do a e-waste. My point is that I know for many other companies that also recycle their old IT equipment and the number of the companies that provide e-waste services is growing. I think it's something encouraging not only for the UK but for the whole world, because I think it's something like tendency all over the world.
What is an electronic component used for?
An electronic component is simply used to resist the flow of a certain current. In theory, it is connected to a circuit board and includes those resistors, capacitors, and transistors.
