Electronics Engineering
Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What is the point of using an inverter charger?
An inverter charger is better to use because it doesn't have a high risk of fire, as other chargers do. They also tend to use less electricity than other chargers.
What of the circuit can be used as parallel to serial converter?
multiplexer can be used as parallel to serial converter.
How do you calculate Potier reactance?
You need the machine open circuit saturation curve as well as the zero power factor test results to obtain the best possible answer. Once you have that you can draw the potier triangle and obtain the value analytically. Please tell this forum if you have these results and I can help you further. Because it involves graphical analysis, it would be easier to e-mail something. I can't find a way on this forum to add any form of graphics..pity

6.concrete furnace
7.tight searching taflers
8.mihed scream
At what frequency does a 350mH inductor have 4.7K ohms of reactance?
Begin with the most basic. Ohms law. I=E/X. Don't know I or E? Then the formula is, XL= 2 x pi x f x L. That is Inductive reactance equals 2 x 3.1416 X frequency in hertz x inductance in henrys.
If frequency is in MHZ, HF. VHF. UHF., radio frequencies, reactance in inductors/coils is small and requires no conversion if the values are expressed in microhenrys and megahertz.
If the question is not just a simple test question and you are dealing with a real world application, one must remember that current runs 90 degrees behind voltage, which is the opposite of the capacitor current-voltage relationship.
What is the phone number for Nintendo America?
1-800-555-1020 is not the correct number. Nintendo number is 1-800-255-3700.
Plug and Play is a technology that simplified attaching peripheral devices. In the past, you had to physically set the settings on the cards you installed. However, not everyone knew what the settings were set to, and they would install something else and there would be a conflict. The cards needed to use different IRQ, DMA, and base addresses. Plug and Play will negotiate with the devices and come up with the best settings that will allow everything to work.
Are Lazaro Instruments qualitiy instruments?
Probably ... depends on user feedback. What may be a quality instrument in one persons eyes may be junk in another's, and vice versa. It's all personal preference.
For 'f' in GHz and 'D' in feet, I always use Gant, dB = 20 log( f x D ) + 7.5
But I think that's for 55% efficiency. If the eff is 60%, that's 20log(60/55) better = another 0.75 dB. So let's make it
Gant, dB = 20 log( f x D ) + 8.25
20 log( 6 D ) + 8.25 = 50
20 log( 6 D ) = 41.75
log ( 6 D ) = 2.0875
6 D = 102.0875
D = 102.0875 / 6 = 20.39 ft = 6.21 meters (rounded, but it looks reasonable; hope it's close)
How much is a Hot Wheels Belt buckle with the logo on it worth?
$80-$100
There are about 10 different Hot Wheels belt buckles that have been produce. They range in price from $5 to $50 packaged. They are found on ebay most all of the time.

How can you get the information about luminance using CCD Camera?
hi all. i really need your help. i have colorimeter which can get the information about RGB, luminance of light source such as LED. but i don't know where the colorimeter get the information from and how? recently i found so many articles about CCD. and i understood, the CCD Camera can get the value of luminance of light source. CCD is just a image sensor. when i take a video of LED , each cell of CCD has information about electric charge and CCD analyse brighteness based on electric charge. and it can be display as a signal. that's just a theory. i need, how can i get the information about luminance!?? i'll take a video of LED using CCD Camera or special colorimeter, and connect it to computer so that i can get the information. does anyone can let me know? please help me thanks
Are Electronic communication always asynchronous communications true or false?
Electronic communication is always asynchronous communication
How do you convert smell to electrical signal?
There are no COTS sensors capable of doing this. The military and police still use dogs to detect smells, but they can't be connected to electronics.
Which IC can be used for 100V power supply?
LM317 can be used for regulated dc power supply upto 37V. For more voltage range, a zener can be connected at the reference pin.
Differentiate parallel circuit and siries circuit?
If two circuit elements (e.g., two resistors) are in series (a series circuit), the current has to pass first through one, then through the other. If they are in parallel, the current has a choice, through which of the elements it passes.
How are electrons generated in a gas filled tube?
As this relates to EE, the electrons are already in there.
Can we respectively control the throws of a 2 form c relay?
A 2 form C relay has a common coil so, no, we can not respectively control the throws of a 2 form C relay. The two throws operate together.
Draw the analog signal for 2B1Q scheme for binary representation of 0011001100110011?
we can answer this question by using the following table.
previous level +ve previous level -ve
Next bits Next Level Next level
00 +1 -1
01 +3 -3
10 -1 +1
11 -3 +3
What would happen to the brightness if you get a smaller bulb?
If smaller means less power for the same voltage, then a smaller bulb would result in less brightness.
If smaller means less voltage for the same power, then a smaller builb would result in more brightness.
A: BY adding resistance to one or all branches will reduce the voltage drop across any branch. But also the current will be reduced accordingly
