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 is the signal from the transducer converted in to an image?
A computer converts signal into an image.
The power developed in a resistor of 24 ohms is 225watt what is the current?
Ohm's law states V = I*R, and power is equivalent to voltage times current, so a little manipulation will get you to:
P = R*I^2
225 = 24*I^2
I = 3.06 amperes.
Can you replace a 2-30 trimmer capacitor with a fixed value capacitor?
Yes you can.
But the variable one is used so that you can very the frequency and it cant be varied anymore if you use a fixed capacitor.
What type of amplifier would be used to drive speaker system of a record player?
An audio power amplifier.
An audio amplifier is designed to amplify frequencies between 15 Hz and 20 kHz. Any amplifier that is designed for this entire band of frequencies or any band of frequencies contained in the audio range is considered to be an audio amplifier.

It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
Where can you purchase Reef flip flops?
There are many places to buy Reef flip flops. The best place would be the Reef website. Other places you can buy them are at Macy's, Zappos, Dicks Sporting Goods, and Amazon.
Does a hollow metal tube conduct as good as a solid rod of the same material?
as in solid rod there has more free electrons which will cause more current than a hollow metal tube of same dia/length/material.
How do you convert capacitors to resistors?
Capacitors are completely different than resistors and there can be no converting between them, whatever that means.
Why is serial transmission preferred for long distances?
Because the costs are small than other kind of transmissions. For example, in case of 8 bits data transmission, parallel aprouch needs 8 wires but serial only 1 (cheapest).
What does a Futaba transmitter do?
A Futaba transmitter sends signals over a frequency to a receiver. It comes with a 2.4GHz frequency technology that makes a radio controlled vehicle reach maximum performance wireless and provide better precision on track or on air.
What are applications of ring counter?
some old enlarge lens-boards just had aplain hole in them so you needed the threaded ring to fix the lens in to the board
What is the purpose of shopping websites?
If a store is far away, you can order an item online, on the shopping website. The shop will ship it to where you live.
You can check what the store has before you go to the store. You can find out if the store has it in stock.
Ferrite bead is a lossy inductor.When the frequency is high the Ferrite bead purely acts as a resistance so high speed noises are absorbed by the FB and it dissipate in the form of heat.
Based on the current rating,cross over frequency the ferrite bead should be select
ANSWER: A ferrite bead is a powder core if a line is wrapped on it that will eliminate RF signal externally injected into the line to interfere with the circuit that the line is going to it. The selection is arbitrary until it does the job. bigger the better. An inductor is also a choke to reduce RF but not as effective and it does have losses on the line
How many led are there in a led screen?
If the question refers to an LED illuminated LCD television, there will be several hundred individual LEDs forming a single panel.
A true LED television uses a separate LED for red, green, and blue dots at every pixel. A 1920 x 1080 pixel television has just over 2,000,000 pixels. Each one needs a red, a green and a blue LED so there will be a total of 6,220,800 LEDs making up the image.
Can a microfarad conevrt into volts?
No! This is a term for capacitance. A capacitor will store a voltage up to it's breakdown limit plus cause a voltage reaction to a following circuit.
When does a capacitor becomes saturated?
When both sides of its plates are full of their respectively charged electrons. This happens very rapidly, depending on the size of the Cap., generally within microseconds.
What are the commercially available batteries?
Thousands of types of several chemical make-ups from many manufacturers.
What determines the amount of potential required to forward bias a unijunction transistor?
Intrinsic Stand-off Ratio
How do you build a CB tube linear?
Have you ever stopped to wonder why they're not available to buy in stores ?
Why Radio Shack and Best Buy don't sell them, and not even Cobra makes them ?
Why one costs a fortune if you can find a guy in the bar who's willing to sell you one ?
Why you never see them advertised anywhere ?
That's right . . . selling them is illegal, because using them is illegal.
If you were to read up on it and get a ham operator's license, you'd know how to build
a high-power linear, but you wouldn't want it anymore.
What was the role of the valves in Colossus?
the first electronic computers were built before the invention of the transistor or integrated circuit chip. They used vacuum tubes for the processing and temporary memory. In Britain those tubes were called valves.
What is the difference between OR diagram and OR circuit?
- OR diagram is a drawing or plan of the digital logic OR function, it is not able to actually do anything only tell a person something about this logic function
- OR circuit is the actual electronics implementing the digital logic OR function, it is actually able to carry out this logic function in a digital device or system
The 110VAC to 125VAC range (not the 220VAC to 250VAC range).
What does negative capasity in capasitors mean?
The amount of power that capacitors can store can vary. But most sizes are larger than the size of the ship and capacitor it can increase by training the energy management.
