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 role of clock generator in microprocessor?

The clock signal in a microprocessor allows synchronization of several components of the microprocessor. The correctness of the computation of the microprocessor depends upon efficient and balanced distribution of the clock signal. The clock generator generates the clock signal.

What are the functions of slip ring carbon brush external resistor in an alternalting EMF generator?

good question the use of slipring carbon brush is to give excitement to the generator , as the carbon brosh contact the rotor slip the rotaion and the speed of the generator increases we can say as an external force by anonrafee blueroz_27@yahoo.com

After market replacement amplifier for infinity stereo amplifier in 2001 sebring coupe?

It is possible but impractical and may not be economically feasable. The labor fee to JUST to remove factory connectors and replace them with industry standard connectors would be cost-prohibitive, even with a factory schematic. Then you have to pay for system design and integration after that. It might be more economical to have the entire audio system replaced with an aftermarket system installed by car-audio professionals. If you still feel the need to replace the factory amplifier try to locate it's schematic by factory part number first then show that to some local electronics tecnicians who may be able to tap in to the original circuits for you. At least in this way you can do your own feasability study at minimal cost for the price of buying the schematics and presenting them for estimates. I am about to tackle a similar project on a Sebring convertible who's power amp took a bath and self-destructed afterwards. It looks like about a full week's work to me. GOOD LUCK.

Plc lamp stand for?

For lighting, PL-C Lamp is the acronym for Philips Linear - Compact (PL-C) Flourescent Lamp.

What is the difference between Fourier transform and Laplace transform and z transform?

Fourier transform and Laplace transform are similar. Laplace transforms map a function to a new function on the complex plane, while Fourier maps a function to a new function on the real line. You can view Fourier as the Laplace transform on the circle, that is |z|=1.

z transform is the discrete version of Laplace transform.

How do you prove that the output of a differential amplifier is the difference of its two inputs?

A: By applying two known DC input with a known gain the output will be there to prove the difference.

What is the Principle and operation characteristic of switching diode?

A: The principle is that is a semiconductor meaning will conduct one way only. A switching diode however will have the least of capacitance across its junction so when it disconnect is faster

How would you make a simple led light emit a high decibal noise when the light is crossed?

You need two devices, a light source, such as an LED, and a photocell such as a selenium cell or cadmium sulfide cell. The output of the photocell can be amplified and connected to a switch which controls an audio oscillator to sound when the light of the LED, received by the photo cell is broken.

Why scr is not suitable for dc circuit?

A: It is OK if a way to insure that the SCR can be shut off otherwise it will conduct forever. the only way to shut off an SCR while is on is to reduce the current below them holding current point or by reversing the polarity briefly

How do you delete complete history on a video game?

if it is an internet game go to internet options and go to delete all

Why the resistance of forward bias is equals to zero nd resistance of reverse bias is infinite?

  • the junction is conducting when forward biased, approaching zero resistance
  • the junction is nonconducting when reverse biased, approaching infinite resistance

neither is exactly zero or infinite

What is meant by drift current in diode?

when ever the external voltage is given the movement of charge carriers produce a current i.e drift current

Does the value of the exciting current of your 3-phase motor depend on the rotor speed?

An induction motor has no excitation, so the question is about a synchronous motor. The rotor speed is determined by the supply frequency. For a given supply frequency and mechanical load, the excitation current can be adjusted to give the best power factor.

What is intrinsic concentration?

in an undoped semiconductor, the number of carrier available per unit volume for conduction is the intrinsic carrier concentration. These are the loosley bonded outermost electrons of the parent atom which can be freed at room temperature hence both type of carrier (n and p) are equally present in the specimen.

What is microfarad?

Fifty millionths of a farad, abbreviated as 50 uF. Farad is the unit of capacitance. 50 microamps DC flowing for 1 second will charge a 50 uF capacitor to 1 volt.

Can foam flip flops get wet?

yes. as long as it absorbs liquids, it will be fine
