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.

Why is absolute zero important?
absolute zero is the essence of nothing and nothing is a quantity of zero.
What do you mean by peak reverse voltage of semiconductor diode?
Peak reverse voltage of a diode is the maximum reverse bias voltage can be applied to diode which does not cause break down.
What is the Difference between image impedance and iterative impedance?
iterative impedance is a particular value of the load impedance that can be found which will produce an input impedance having the same value as the load impedance.When connected at one end of the port produces an equal impedance when looking at the other.
Image impedance-Two impedance's of two port network,which will terminate the port simultaneously in a way that, at each port the impedance seen in both directions are equal.
There is no coupled capacitor in existence that i know. Capacitors can be used to couple or decouple a signal
What is the purpose of the color bands on a fixed resistor?
The colour bands indicate the value and tolerance of the part. The colours are specified in in standards published by the "Radio Manufactures Association" in North America. One (of many) handy pages that help explain how to read the code is here : http://www.radioremembered.org/rescode.htm .
There are many other similar pages out there.
The advantage of a semiconductor strain gauge over the normal strain gauge is that?
it is more sensitive
small gauge size
low hysteresis
What is halm Jet press dry offset?
Halm Dry offset presses use a polymner plate (like a letter press) this would transfer the ink to the blanket instead of the subtractive metal plate used on wet ofset press's. The plate cylinders are magnetic to allow the plate to adhere to it. Some people use adhesive backed polymer plates to achieve the same result. All dry offset presses can be converted to wet offset but it is costly. You would need new plate cylinders, complete dampening systems, dampener recirculating tanks, water form arms, new oscillating bushings and new electronic controls for the additional water motors added to the press. These components are available after market for a lower cost.
What if the difference between fiber optic and satellite communication?
Satellite versus Fiber Optics communication
1- Fiber optics communication is quicker but satellite is slow in communication.
2- Fiber Optics communication higher bandwidth but Satellite Lower Bandwidth.
3- In case of any fault we can easily repair Fiber Optics but Satellite can not be repair.
4- Fiber Optics initial Cast is low but Satellite is very High.
5- Many People want to communication during jogging, driving, sailing and flying these all possible in Satellite Communication But Fiber Optics not use for them.
6- Fiber Optics is Very costly for long range communication but Satellite is low for long range communication.

Indians used smoke to communicate from a distance.
Also smoke signals are used to signal aircraft landing points, and people in distress, To make a smoke signal:
Make a small fire,
Addfresh greenery to the fire (leaves),
and leave the amount of smoke generated because of the greenery will create enough of a signal to attract the attention of any person with any knowledge about survival skills.
What is the full form the technical terms of Rx and Tx in converters?
Rx= recipe = you take
Tx= treatment
recipe for the treatment
What is the difference between electronic engineering and electronic engineering technology?
Electronic Engineering Technology makes you a technologist engineer.
You are an electronic, technological engineer meaning you are hands on in the design or development of technological equipment invented or advanced by the electronic engineering field.
Do not be mistaken, electronic engineering technology does not make you a technician. Technicians are low level white collar jobs with the most limited requirement in education and often, it can be done on the job with certification issued by the employer.
Technicians are basically maintaining and servicing a specific technology such as audio equipment or networking devices. Their knowledge and skill set will be limited to a specific category of technology. Most people will explain Electronic Engineering Technology degrees incorrectly and lead you to believe you are an underling servant to a real engineer which is complete B.S.
The electronic engineering technologist will have a relative understanding of all current technologies but it is of course superseded by the electronic engineer's knowledge and understanding.
An electronic engineer is educated with a focus on math, theory, development and advancement. For example the technologist or, technological engineer is designing a new amplification system and needs an operational amplifier to perform a task that none is existence can currently perform. It is now the engineer's duty to use his/her superior math and theory knowledge to design that op amp. Much if not all of their work is done on a drawing board and a computer.
At the lowest level, the technician is the repairman that fixes the device if it breaks down because it's a simpler job in regards to knowledge but more demanding and timely so the employer isn't going to waste the technological engineer's resources on said duty.
What are the three main power losses that contribute to transistors junction temperature?
Switching losses
Conduction losses
How many millions are in a quadrillion?
1,000,000,000,000,000 = 1 quadrillion
1,000,000,000 = 1quadrillion / 1 million
What is the difference between a transparent flip flop and a master slave flip flop?
I never heard of transparent flip flop and i think it refers to a 'd' flip flop where the output will follows the input with the clock. a master slave referred as j-k do not follow the input not until the master tells the slave to flip
What is type 1 and type 2 semiconductors?
Type 1 Semiconductors: The bandgap of one semiconductor is completely contained in the bandgap of the other one. In double heterostructure design carriers will be confined in the smaller bandgap material. this structure is used to form barrier/quantum well in Multi quantum well lasers and LEds
Type II: like Type I The bandgap of the two materials overlap but the changes in the conduction and valence bands change sign. this type of materials do not use for light emiiting application as carriers can not be confined.
How does a transistor tester work?
very unreliably it can only tell if it is good but not how good and will tell you if bad but not how bad. it is only good for pass no pass testing.
How is an multimeter connected to take a measure?
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
What are the 4 parts of a cathode ray tube?
four parts of CRO:
1-crt
2-horizontal section
3-vertical section
4-power supply
What are the classification of JFET?
Junction Field Effect Transistor are classified as hi impedance devices
