Are antistatic wrist wraps necessary?
If you handle component boards / motherboards, etc. only by their edges, or occasionally touch a water pipe or other earthed metal fittings, to dissipate body static, then an antistatic wrist strap is not necessary. I don't wear one, but it depends on how confident you feel - if in doubt, wear one.
A tubular battery is one type of popular battery designs with parallel tubes that contain lead oxide. Thy are designed with openings that offer easy maintenance. The batteries are more efficient with less water loss and have a fast charge rate.
What is automatic voltage stabilizer?
An Automatic Voltage Regulator (AVR) is a special piece of electrical equipment which is designed to maintain its output voltage at an almost constant value even though:
- the input voltage supplied to it may vary considerably within the voltage range for which the AVR was designed
and
- the amperage or current drawn by the load it is serving may vary considerably within the amperage range for which the AVR was designed.
What is the most powerful laser colors?
The CO2 laser is used for cutting steel as a routine industrial process, and with an excellent surface finish. These operate in the infra-red at about 10 micron wavelength.
However, insofar as the colour itself is concerned, the higher frequencies (blue and violet) contain higher energies.
What is the use of ic D8255AC-2?
It's a programmable, general-purpose input/output device designed for the Intel 8080A/8085A processor lines. Basically it's a chip you can use as interface to various other electronics - storage, displays, ports etc. It has some features (like the ability to drive printer and display interfaces directly) that make it a one-stop solution to interfacing with many devices (that is why it's general-purpose).
What you do is send data from the CPU to this chip, and then switch its communications to another chip - the D8255AC has various interface options (and so is programmable) for different methods of communication that it will handle for you. It can be an input, an output, or both. You can hook up many devices (other chips) to it at the same time and communicate with them accordingly.
The D8255AC-2 is the 5MHz system clock variant (there is a 4MHz variant, the D8255AC-5).
Please keep in mind that you still have to make input/output levels (voltages) match, by using other chips in-line if required.
How does connecting a battery to a circuit make charge flow?
well its simple whoever asked this question is thick. It gives charge because a battery is the source of electricity therefore firing up the current and electron.
Where can you get a replacement electronic control module for 1991 Lincoln Mark VII?
most ford and Lincoln dealers can get this module for you
Answer
Most autoparts stores have the ECM. But you may also have to change out the Pickup located inside the distributor which requires the distributor to be taken apart buy removing the gear. Or you can buy a rebuilt distributor but make sure is matches the old ones gear. Some gears are made from the wrong metal and break (HO vs non HO engines). Make sure you have a book with picture before attempting to do this. In my experience I paid $400 to have the ECM changed and the problem ended up being with distributors pickup (the 87 LSC would randomly not start) after doing the job, I took it to a professional to get the engine timed($60)-I just could not get it to work right(high idle no power). Always use premium gas.
Why do you use npn transistors in an astable multivibrator?
You can create an astable multivibrator with PNP, NPN, FETs, or even with NOR gates, NAND gates, or NOT gates. In fact the escapement movement in a mechanical watch is a species of astable multivibrator.
What makes a video a powerful multimeda tool?
Video is better than picture, because it shows a motion of things, it shows how something is changing with the passage of time.
Video is better than audio, because we have not only a sound, but a picture in motion too.
Video is a combination of audio and motion picture, it has the greatest influence. You see and you hear.
Does a bigger battery last longer than a smaller one?
If we assume the same battery chemistry and quality, and the same drain, then the bigger cell will last longer than the smaller cell, as the bigger size means it'll hold a bigger amount of energy.
Is it true that projectors can't project black?
Yes - it's true !... The colour black is simply all the other colours being absorbed by the object in view.
Are rubber duck antennas good for receiving?
All rubber duckies are good for everything. Even the gray ones.
What is the alpha beta teta of a bipolar junction transistor?
- alpha is the common base current gain = Ic/Ie.
- beta is the common emitter current gain = Ic/Ib.
What does a comparator do in electronics?
A comparator is an operational amplifier used without a feedback circuit. The output of the comparator will be high when the voltage of the non-inverting input is below the inverting input, and low when the inverting is above the non-inverting input. The output is undefined - i.e. can by anything - when the voltages are equal.
How do you record videos on your Kindle Fire HD?
In addition click the links and watch both videos.
What is the net charge of copper atom if it gain two electrons?
Cu(2-) does not exist, because Cu does not gain electrons at all being a metal. When it gives off two electrons Cu(2+) ions are formed.
Why is there no listing for the Electronics Technician program wwwETcoursecom?
There is a syllabus for the course posted on the Virtual Campus by Geroge Brown College. You got a link if you want to surf on over.
What kind of diode that has 4 legs?
This is stupid question, how about how many leg are there in 4 way bridge rectifier. the answer is 4 legs.
