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.

How do you open idx files?

This comes from: http://www.filesuffix.com/extension/idx.html

"IDX file is a LaTeX Unsorted Index Data. It is an makeindex input file. LaTeX is a high-quality typesetting system, with features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents."

At the bottom of the page it says:

"Open OPX Files Open OPX Files with OrgPlus. Download Free Trial."

How does CMOS work?

CMOS is the little battery in the computer's motherboard which keeps the computers internal clock running.

Do capacitors store electrical energy?

Capacitors act like tiny storage batteries made of two plates separated by a thin insulator or air. When one plate is charged negative and the other positive, they build up a charge that remains when the current is removed. When its power is required, the circuit is switched to conduct current between the two plates, and the capacitor releases its charge.

AnswerCapacitors don't really store charge at all. They allow negative charge to be transferred from one plate to the other, thus establishing an electric field between their plates. But there is no net increase in charge -the amount of charge on the capacitor's plates, after 'charging', is exactly the same as there was before 'charging' -it's just moved around! What capacitors 'store' is energy, not charge.

How do you connect a 2 ohm amplifier to a 4 ohm speaker?

Yes you can. 2 ohms is as low as you can go with that amp MOST car subs have 4 ohm voice coils. The bigger the number, the less low bass frequency run two single voice coils subs and you'll be fine. It's a myth. There is really no 2 Ohm amplifier on the market. And there never was. The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout << Zin. That means the output impedance of the amplifier is much less than the input impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. Zout = Zin/Df. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 4 ohms, the output impedance of the amplifier is Zout = 4 / 200 = 0.02 ohms. You see, there is no "2 ohm amplifier" on the market with a 2 ohm output impedance. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".

How does capacitance cause signal degradation?

A capacitor is composed of two conductors that are separated by an insulator. This is a simple definition, but it says a lot about capacitance, and it says it very well. By this definition, there could be capacitance just about anywhere in a power system or circuit. Yes! There could! And there is! Capacitance offers "resistance" to alternating current (AC) signals called reactance. The higher the frequency, the less reactance there is and the better the signal will be able to pass through the capacitor. In modern electronic equipment, there are lots of circuit pathways and lots of components in the circuits. This leads to a lot of distributed capacitance in the circuit. This distributed capacitance represents a lot of little pathways for signals to "jump gaps" in the circuit. Signals will avoid going through the components and devices and also avoid following all the pathways it is supposed to follow. The signals will be "shorted around" components or "shorted to ground" in other pathways. This combines to effect signal loss or degradation. The higher the frequency of the signal put through a circuit, the more loss there will be to the signal due to distributed capacitance.

Which is faster Latch flip flop?

The terms "flip-flop" and "latch" are applied to a variety of circuits, and there is some overlap in the meaning. As far as I know, there is no official meaning; like all English words, the meaning is somewhat flexible. Generally, latches have less clock hardware built into the circuit, making them more flexible. If you don't need the clocking, you can probably perform your function faster with a latch than with a flip-flop. If you do need the clocking, you may end up performing your function slower if you add the necessary hardware to a latch, rather than just using a flip-flop that already has it built in.

Why you use silicon not germanium in SCR?

because lekage current of silicon is less than germenium

What is wobbuloscope?

A wobbuloscope consists of a sweep generator, CRO and a marker generator, which can be tuned to frequencies corresponding to the vision carrier, associate of sound signal as well as the IF of the T.V. receiver

Why absorbance is negative log of trnsmittance?

there are two errors may occur in this sitution.

1.mechanical error.

1.labour error.

ps. standard addition is an exceptional case.

What is the function of an electrical coil in a basic circuit?

There are a couple of examples that come to mind where there is a coil in a circuit. One is, the coil is used as a choke to block harmonics from going down the electrical line. Another example of a coil in the line is the coil in a magnetic contactor. When this coil is energized the contacts of the magnetic contactor close.

What are the advantages of wireless communications?

A: The advantage is that no wires are needed to communicate. Example printer to computer. Obviously there are some disadvantages the power output is very limited in range. Why because if not limited it may interfere with other hubs or worst stealing info with a receiver.

How conveyor belt counts number of items passing?

A; The conveyor belts actually is a media. Actual count is done by electronics optics for every interrupt a counter is increased by one. or by switches that progress a count for each switch closure

Why dc output voltage of a bridge rectifier varies with the load current?

aA

A: the output of a Bridger's rectifier will always follows proportionally to the load since it does not regulate the output it merely transform AC TO DC

Why ordinary transistor is known as bipolar junction transistor?

Transistor is known as bipolar junction becoz it has 2 pole. Input is given to the 2 junction and output is taken from to junction

Why is ce configuration employed in transistors?

for the same reason cs is employed with FETs and cc is employed with vacuum tubes: high voltage gain & high current gain.
