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 approximate turns ratio of the centre-tapped transformer used?

It depends on the voltage ratio of the transformer. If you know the primary and secondary voltages, then you can work it out for yourself.

What is a IC extractor?

An integrated circuit extractor is also known as a chip-puller. This tool helps to safely and quickly remove an integrated circuit from its socket without bending or damaging the pins. It is a tool commonly used in computer manufacturing and repair.

What is the criteria of Electronics companies?

The first Criteria of electronics companies is first class in BE & the person should have proper knowledge about the electronic circuits & Basic electronics fundamentals....(This is for an EC Engg only...)

What is signal of disapproval?

A signal of disapproval might include something like a frown or a shake of the head. When a person does not approve of another person's actions, he or she will often make a face that looks angry.

Can DC series generator start on no load?

yes.it is possible to start dc series generator on no load condition

Can there be a different voltage across each component in a circuit?

Yes, if it is a series circuit. In an ideal parallel circuit, there is equal voltage in each leg. In a real circuit, results may vary if there is voltage loss in the wiring.

Does the impedance of an RL series circuit varies inversely with the frequency?

The simple answer is no. The impedance of an R-Lcircuit is the vector sum of the circuit's resistance and its inductive reactance. Resistance is determined by the length, cross-sectional area, and resistivity of the conductor (although its 'a.c. resistance' is proportional to the frequency squared), whereas the inductive reactance is directly proportional to the frequency of the supply.

How do you obtain n type semiconductors?

by adding pentavalent impurity in d pure semiconducters (like intrinsic semiconducters) is called n type semiconducters

What is an electrostrictive transducer?

any device that converts energy from one form to another usually electrical to mechanical by using the property of all electrical non-conductors, or dielectrics, that causes them to change their shape under the application of an electric field

What is the limitations of pn junction?

Limitations:

1.)It Can be utilized as rectifier as a part of DC Power Supplies.

2.)In Demodulation or Detector Circuits.

3.)In clasping systems utilized as DC Restorers

4.)In section circuits utilized for waveform era.

5.)As switches in computerized rationale circuits.

Why Phase Shift on transistor amplifier?

because that's how God intended the way of the world to be..

What is the need of non uniform quantization?

problem with uniform quantisatonis

1.real audio signal is concentrated near zero

2.human ear is more sensitive to quantisaton error at small value

using non-uniform quantisaton

quantisaton intrval smaller near zero

Non uniform quantization reduces the signal-noise ratio at low signal levels.
