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.

Will magnetic field is produced when current is passed through a thick conducting sheet?
Yes,,,a current carrying conductor wil produce magnetic field around it.
What is Saturation voltage of bjt?
It is the CE (collector - emitter) voltage at a given collector current when the transistor is fully on. Increasing the base current will not lower the CE voltage any more once saturation has been reached.
CIF stands for Common Intermediate Format, and was used to standardize the number of pixels in teleconferencing systems. The typical video resolution for CIF is 352 x 288 pixels.
What are the devices which converts sound signal into electrical signal other than microphone?
One is the hydrophone, used to pick up sound waves underwater.
To regulate a powersupply. The variations of voltage will be nullified by this ic. For example a three legged ic say number 7812 gives 12v dc supply if you are applying a voltage of 13 to 24vdc at a maximum current rate of 1 ampere. If applied voltage is 24v the dissipation will be approximately 12w.
How ceramic capacitors can do filtering in replacement of electrolytic capacitors?
Electrolytic capacitors do a very good job of bulk filtering, but they have poor high frequency performance due to distributed inductance. The ceramic capacitor has excellent high frequence response, and will often be used in parallel to the electrolytic to filter out fast rise time step changes in current demand.
Why is it unwise to store electronic equipment on a carpet?
i dont get any answere maybe i will try a next site.
Carpets tend to favor the accumulation of static electrical charges: With movement across carpets and low ambient humidity conditions sensitive electonic equipment can be damaged by resulting electostatic discharge.
Why can't extrinsic semiconductors be fabricated from bivalent and hexavalent elements?
My thinking is ... If intrinsinc semicoductor is doped with Hexavalent Impurity, then energy level of outermost orbit of hexavalent atom, will fall below than that of pentavalent atom, so more amout of energy will be required to move this newly generated electron to move from fermi level to conduction band of semicondoctor. And vice versa for Bavalent.
Can you swap IN5408 in a power stage of a tube amp with UF5408 diode?
Yes you can. The UF is a significantly faster diode. The peak forward surge current is 50 amps less, but apart from that they have much the same characteristics.
How do you fix my ipod port charger after water damage?
You can't necessarily unless you plan to rip it apart and buy parts for you iPod which I don't recommend of you have no experience the best option is to take to get repared most water damage fixes don't cost much
What is the distance up to which the clap switch receives sound signal?
It's not the distance, it's the decibel.
Which material we need to show a 9 volt power supply?
Well it depends on several things, does it need to be AC or DC? how much amperage must it be able to supply?
For a very basic power supply you could us:
A Step-down transformer
A bridge rectifier (4 diodes of sufficient voltage and amp rating)
Two capacitors; one at 1000uF and one at 0.01uF
A 9 Volt voltage regulator (LM7809 is good)
Depending on transformer and rectifier, this'll deliver 9V at up to 1A
If the current increases what happens to resistance?
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will cause an increase in resistance.
4 How do you determine current in a parallel DC circuit?
The current in each individual component of the parallel circuit is equal to
(voltage across the combined group of parallel components) / (individual component's resistance).
The total current is the sum of the individual currents.
==============================
Another approach is to first calculate the combined effective resistance of the group of parallel components.
-- take the reciprocal of each individual resistance
-- add all the reciprocals
-- the combined effective resistance is the reciprocal of the sum.
Then, the total current through the parallel circuit is
(voltage across the parallel circuit) / (combined effective resistance of the components).
What is the basic parameters of transmission lines?
the basic parameters of transmission lines are R,L,C and G...........
Will a 1080p home theater system work with my Panasonic 1080i CRT HDTV?
1080 is a video standard and has nothing to do with the audio. Connect the stereo audio outputs of the tv to the inputs of the home theater. Check the HT menu to be sure it is set for multi channel audio on the input you are using.
Where can you get a NI-CD 2.3A700mAh 8.4V battery?
The question is actually, Where can you get a NI-CD 2/3A700mAh 8.4V battery? Wiki wouldn't let me put a slash mark between the 2 and 3.
I have an airsoft gun and the battery broke so i need to find another battery of this type.
Please help!!!!
I want to use my airsoft gun.
What happens if commutator of DC generator is removed?
If the commutator is removed from your generator, you (if you connect slip rings) get AC supply instead of DC supply. the function of the commutator is to convert AC to DC supply and vice versa.
Additional Answer
Removing the commutator will also prevent you from connecting the output of the generator to its load. Remember, the generator's armature is spinning!
Why are there often so many steps between the original signal event and the cell's response?
Each step in a cascade produces a large number of activated products, causing signal amplification as the cascade progresses.
How can you rotate the stepper motor to different angles?
A; stepper motor can rotate to various angle if the resolution is infinite then the rotation will be infinite. however practically is set to step a certain angle per step
Are 1N4001 diodes suitable to be used in this rectifier circuit?
There is insufficient information in the question to properly answer it. Please restate the question.
