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 a program visible register?
the registers that are used during programming and are specified directly by the instructions.
Used to store data when the data is not being used in memory?
A storage device is used to store data when data is not being used in memory.
What is difference between telecom and datacom?
In generic terms, Telecom is communication of voice from the sender to receiver with the help of hardware and softwares.
Datacom, is transfer of non voice (ie, data) from the sender to receiver with the help of hardware and software
Were did the first telephone operated in Australia?
Alexander Graham Bell famously demonstrated his invention by communicating between two rooms of a Philadelphia boarding house in 1876, and later that year showed it at Philadelphia's Centennial Exhibition.
The first commercial telephone in Australia was installed in 1879 by a Melbourne engineering firm, Robison Bros. to link their city office with their South Melbourne foundry.
What is the difference of earth and insulated return in an electrical system?
An earthing system is a system where circuits are connected by a ground. An insulated return system is how power is transferred to trains.
What is an effective way for a society to deal with diversity?
- Following the rule of law
- Accepting the legitimacy of the laws that are in place
- Protecting minority rights
A cadet engineer is an engineer in training. They are in the process of receiving training in the different areas of engineering. They assist various departments with civil works. They are usually in the process of receiving a bachelors degree in engineering.
Parallel with any component like R or C or L or any 2 nodes of the circuit. Feel free connecting VMs anywhere in your circuit keeping in the proper Range/scale selector/AC-DC selector . That makes no damage
How do you install a linear CB amplifier?
You don't. Linear amplifiers are illegal for CB use. The maximum input into the final stage of a CB transmitter is 5 watts.
What are the applications of statistics in electronics and communications engineering?
In electronics engineering the only statistical methods that reasonably can be applied are the descriptive methods and least square curve fitting ones.
In all cases the inferential statistical methods should be avoided.
Inferential methods try to retreive a theory from a data set.
Correct science works the other way around.
What is binomial array in antenna?
Binomial array is an array in which the amplitudes of the antenna elements in the array are arranged according to the coefficients of the binomial series...
The need for a binomial array is
i) In uniform linear array as the array length is increased to increase the directivity, the secondary lobes also occurs.
ii) For certain applications, it is highly desirable that secondary lobes should be eliminated completely or reduced to minimum desirable level compared to main lobes.

How do you load a Glenfield Model 60?
Unscrew the magazine tube (located near the muzzle of the gun) and pull it out until the ammunition feed port (located on the bottom of the magazine tube) is open. Feed the ammunition in primer first and drop down the tube. Once loaded, push the tube back down and screw to secure. Cycle the action to load the ammo. Be careful and have fun.
What are h parameters of a transistor?
the h parameter or the hybrid parameters of a transistor helps us to analyse the amplifying action of transistor for small signal .it is necessary for practical purposes.
In generally there are four type of h parameter.these are :
h11
h12
h21
h22
How does a resister pack work?
resister is nothing but a 'clay' which will reduce the flow of current. There by limiting the volt.
What are the different types of magnetrons?
There are 3 (three) types of magnetron design: "hole and slot", "vane" and "rising sun" the names come from the anode cavity cut out shape. The anode is the outer larger metal once you remove the permanent magnets. The hole and slot has small circular chambers "holes" with slots directed to the center. The vane has trapezoidal shape chambers with the opening facing the center. The rising sun has rectangular chambers with of alternating depth radiating from the center. It looks similar to the rising sun pattern from the WWII Japanese flag. In all the cathode is in the center and the theory of operation can be found in "NEETS Module 11: Microwave principals" (a military electronics training manual).
How do you draw a circuit diagram of an electric blanket?
The way I have done this with things such as heaters, window defrosters, etc. is to model the heating element as a resistor (or a set of resistors in different parallel and series combinations, based on the layout). The wire used in the electric blanket (the heating elements) should have a specific resistance per length; calculate the length of the different sections, and create a lumped resistive element of this total length.
What Light frequency equals 42.8 kHz?
42.8 kHz is hardly a light frequency. In fact, it's hardly much of a radio frequency.
It has a wavelength of over 4.3 miles, and is capable of communicating only very
low rates of information, like the time code to the 'atomic' clock in your house,
four times a day.
For comparison, the longest wavelength of visible light is about 0.000026 inch .
Definition of buffer in digital electronics?
A buffer is a means of isolating a signal source circuit from the loading circuit. They are generally needed when the signal source does not have sufficient capacity to deliver the current demanded by the load circuit. If buffers are not used, a problem called input loading results and this may cause the circuit to malfunction or to become damaged.
In digital circuits, the buffers reproduce the sequence of 1's and 0's received from one circuit and make them available to another circuit at a higher power level. A buffer is like a non-inverting amplifier with a gain of unity.
P=v*i i=p/v=0.5/3=1/6 (a)
Wavelength in meters for 13.56 mhz?
You would also need to know the speed. If we assume it is an electromagnetic wave:
300,000,000 m/s divided by 13,560,000 Hz. = about 22 meters.
