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 difference of peak and rms value?
RMS stands for "Root of the Means Squared", and is a mathematical method of defining the "operating" voltage of a sine wave power source.
Typical home lighting and outlet voltage presently is 120 VAC (volts alternating current), 60 Hz. (Hertz, formerly referred to as "cycles per second".)
But the PEAK voltage is the absolute maximum voltage at the "peak" of each sine wave of voltage. Mathematically, the "Peak" voltage is 1.414 (which is the square root of the number 2) times the RMS voltage, and conversely, the RMS voltage is 0.707 times the PEAK voltage.
In which configuration does a diode conduct?
Forward biased is the configuratiuon that a diode conducts.
What is the difference between a voltage converter and a voltage regulator?
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.
Why do wires often have plastic wrapped around them?
Well plastic is a insulator which causes the electrons (also known as electricity) to stay in place. So wires are electrical conductors which means electrons to flow through it and since humans are "fair" electrical conductors it will cause us to get shocked from the electrical charges. Understand? :)
How do you wire 2 8 ohm subwoofers to a 4 ohm amp?
Hook all the negatives together, and hook all the positives together. you would have 2 wires for each. one from the amp to the first sub, and another going from the first sub to the second.
Capacitors are linear components. A linear component is an electronic component that has a linear relationship with current or voltage in an electronic circuit.
Resistors are the most common example of linear components, along with capacitors and inductors. Linear components refer to components whose output and input have a proportional relationship. For example, the relationship between the voltage across the metal resistance element and the current can be considered to be linear when the temperature remains unchanged. Metal conductors and electrolytes also have this characteristic. Electronic components have a lot of this relationship. Poor-quality components will appear "linear distortion" under certain circumstances, that is, in such a case, the input quantity and the output quantity no longer satisfy the linear relationship.

Why FMCW radar has better range resolution than CW radar?
FM CW radar sweeps the Radio Frequency over time. Time in Radar equates to range and results in a high spectral density at every range. CW radar has a much lower spectral density and does not code range with frequency in the same way.
What is redundancy in an electronic system?
This refers to building or designing in to the equipment a number of systems that can "take over " if one part of the system fails to work. Some people call that a built-in back up system.
AnswerAs in a computer system, you would have 2 drives, both with the same exact information on them. When you write info to the drive or load a program on the one drive it loads it on the other drive. If one of those drives goes bad, all the info will be on the other drive and the system will continue to run. Of course you will want to replace the bad drive and copy good drive info to the new drive so that it is again a redundant system. AnswerRedundancy in an electronic system means to have components, which are critical in the working of a device, duplicated. This ensures a good amount of reliability in the working of system. So only critical components are duplicated and that too in applications like Space shuttle electronics or any other application whose operation is quite critical in itself.This makes sure that even if one of the redundant component fails another one will still be working to ensure the operation, however it might degrade performance but wont stop the working.
AnswerRedundancy can also refer to logic systems. This is when two or more logic gates cancel each other out and become unnecessary, for example two NOT gates in a row would be pointless, therefore they are redundant and can be removed. This is a common technique used to reduce the components in a system, and is a technique often applied when doing replacement such as NAND replacement or NOR replacement. However...Some designs often feature a few NOT gates in a line, but are not removed. This is not seen very often these days, as it's a bit of a dodgy fix. It is simply used to create a time delay, so a signal doesn't arrive at its destination too quickly.REDUNDANCY is the art of making a system more reliable by allowing a redundant system to perform the same duty without failing the primary system How redundant can a system be built ? It will reach a point where any additional redundancy could make the primary system fail because of it. It a question of reliability
Answer
In smart plant Instrumentation sometime we use Redundancy feature. It is just like stand by. In automation sometime we make a logic in which when one PLC fails to work then another PLC will resume the process without affecting it. it is also applicable in case of field instruments in Chemical Process Plant, Power Plant etc.
What is positive peak clipping?
Friend,
This is pretty difficult to explain without maths and a diagram, but I will give it a try.
If you have seen a sinusoidal wave, which is like the "electrical component" of an electromagnetic wave. (Well, just imagine a wave), from zero it goes up to a certain level (called a crest) and to zero level and goes to a negative level (called trough).
In some applications, like voltage regulators, you do not need the wave to the highest level. So what you do is to chop off the topmost part of the wave so that it meets your needs. The level of the clipping (chopping of the topmost part) is determined by the circuit.
If you chop off the negative extreme (trough), it is called negative clipping.
Application of other conductors which does not obey ohms law in a circuit?
Ohms law is a law; all conductors must obey it. A simple form of ohm's law is V = I / R. The only control a conductor has on this equation is in the 'R'. Super conductors, for example, have a resistance that approaches zero at certain termperatures. This does not mean that they break the law, though.
AnswerOhm's Law describes a linear relationship between the potential difference across a conductor; it has nothing to do with the relationship between potential difference, current, and resistance.
The equation R = E/I is derived from the definition of the ohm, and not from Ohm's Law. This equation applies whether Ohm's Law is obeyed or not.
In fact, relatively few conductors obey Ohm's Law. Those that do are termed 'ohmic' or 'linear' conductors; those that don't are termed 'non-ohmic' or 'non-linear'.
Simply put, if the graph representing current plotted against a varying potential difference is not linear, then it ain't obeying Ohm's Law!
A ground fault circuit interrupter is the device used to de-energize the circuit.
What would happen if one bulb burns out in a parallel circuit?
Nothing much will happen except the same bulb will not blow..
A: A DELTA transformer is a 1:1 voltage transfer delta to Y IS 1:2 voltage transfer. That is for 3 phase system, If the phases are not exactly matched or the voltage is not exactly right then on a Y setup there will be circulating current at the common node.
How do you fix the error HDMI-HDCP outlet is blocked?
"HDMI-HDCP Outlet Blocked" means you are attempting to play copyrighted material into an output/input configuration that might not detect copy protection.
Either disconnect/disable all the other outlets, or don't try to copy protected material.
to prevent the high voltages The main purpose of an opto-isolator is "to prevent high voltages or rapidly changing voltages on one side of the circuit from damaging components or distorting transmissions on the other side."[2] Commercially available opto-isolators withstand input-to-output voltages up to 10 kV[3] and voltage transients with speeds up to 10 kV/μs.[4]
Do both holes and electrons be regarded as the current producer?
No. They don't produce current, they only transport it.
Why were researchers looking for a replacement for vacuum tubes?
Bell Labs researchers were unsatisfied with the low reliably, high power usage, and large size of the vacuum tubes that needed to be used in the telephone switching and long distance trunk systems of the 1940s.
Does voltage regulator increase or decrease the current input?
A DC voltage regulator gives a constant output voltage provided the input voltage is at least 1.5 v higher, up to a given limit. The input current is slightly more than the load current, because a small amoutn of current is needed for the voltage regulator circuit. Check the datasheet of the component which you are using to find the limits. 7805 IC can give upto 1A of current if there is adequete heatsinking.
Do jailbreak means stealing or just copying?
Neither. It is circumventing the built in restrictions that prohibit you from downloading software from other than the approved source. It is a form of contract violation and, as such, deprives you of legal remedies due to malfunction and it could theoretically constitute a civil violation on that basis alone.
As far as stealing or copying that "unapproved" software, that is a separate issue. There is risk there as well, but the question did not ask that.
