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 are advantages of logic circuits?
A: The advantage is that there is no mistakes if the function is proper. The only mistake there can be is the human telling what to do logic is a study of how to make a machine interpret and execute commands flawlessly even though the machine is very dumb itself.
Why logic gates are called as logic gates not boolean gates?
Logic gates are the basic building blocks of digital circuits or systems. these digital circuits are used to implement several combinational and sequential operations. these operations include starage, timing, arithmetic, coding, communication etc. Hence, implementing the boolean algebra is not the only purpose where logic gates are used, hence, it is opt to call them as logic gates rather than boolean gates.
Why is a current in a circuit never used up?
Kirchoff's Current Law: The signed sum of the currents entering a node is always zero. A consequence of this is that, for series circuits, the current at every point in the circuit is the same.
If this does not answer the intended question, please restate the question and provide more information as to what, exactly, you are looking for. "Used up" is a vague and non-scientific term that does not entirely make sense.
AnswerElectric current is not 'poured' into a circuit, like water from a kettle. Current is 'drawn' from the voltage supply by the load. It is a load that determines how much current is drawn for any given supply voltage. 'Heavier' loads (i.e. lower resistance loads) draw larger currents, while 'lower' loads (i.e. higher resistance loads) draw less current.
What is the importance of determining of resistor values?
it is used to check or verify how much current pass through the circuit using voltage source.
Why is dc current used in the excitation of generator?
The field current is used for the excitation of generators.
AnswerYou use DC current, because you want the resulting magnetic field to be constant. If you used AC, the resulting magnetic field would vary in both strength and direction.
How much current flows through a 5k resistor connected to a 20 volt source?
Use the equation V = I * R
20 = I * 5000
I = 20 / 5000
I = 0.004 Amps
The answer to your question is 4 mA of current will flow through the resistor.
Summing is the blending of audio signals (tracks) into a stereo mix. It is one of the final steps in the recording process, usually coming immediately before mastering (unless the engineer is summing groups of tracks, such as drums, separately). Commonly performed ITB (Inside The Box, meaning digitally) in modern digital audio workstations, OTB (Outside The Box, or on an analog mixer) summing is said to provide a slightly 'bigger', and more professional sound, although this is the source of much debate in the pro audio world.
A 555 time circuit is a circuit chip that can be used for a variety of applications. some include: clocks, time delays, countdown timers, and other time-circuits.
What are the five basic elements in a 555 timer IC?
Inverter, comparator, RS flip-flop, and transistor
Describe how a battery causes electrons to move in a circuit?
The electrons don't actually move the electricity; the charge moves. The electrons slowly drift in the opposite direction from the charge.
What is difference between IC and SoC?
A System on a Chip (SoC) is a type of integrated circuit that specifically refers to the powerful processors found in a personal computer (PC). The idea is to combine different components in a computer onto one chip.
Encryption algorithms AES is FIPS 140-2 compliant?
Properly implemented, AES is FIPS 140-2 compliant.
A module implementing AES must undergo evaluation via the Cryptographic Module Validation Program (CMVP) to be certified as FIPS 140-2 compliant. Federal agencies and departments can validate that the module in use is covered by an existing FIPS 140-1 or FIPS 140-2 certificate that specifies the exact module name, hardware, software, firmware, and/or applet version numbers.
The mini water-proof GPS system called the IPX67 has an overall rating of 8.0 out of 10.0. Overall, it's a decent mini GPS system. However, many tend to complain that the battery dies quickly.
When a voltage is applied across a diode and current flows we say the diode is what?
One description would be forward biased.
Why is a common collector amplifier is called buffer?
Since its input impedance is much higher than its output impedance it is also termed a "BUFFER" for this reason it is also used in digital circuits with basic gates...
What type of a simple machine is a screwdriver?
Most say it is a lever, but i know for fact that it is actually considered a wheel and axle.
-
I'm in proving this and actually it is a lever because i was just taking a test that asked this question and it did not give me the option of a wheel and axle but it did give me lever.
Edit~
The first person to answer was, in fact, correct. To the person who last improved the answer: Some people consider it a lever; it is actually a wheel and axle.
A lever is a rigid object that rotates around a fixed point, like a seesaw, while a wheel and axle is two circular or cylindrical objects that are fastened together (The handle and the metal rod) and they rotate around a common axis (the screw)!

What is the main function of a power supply unit?
The name tells you - it supplies power to the device it is part of.
How many watts in a 320 volt dishwasher?
The rated voltage of an appliance is no guide to its power rating. To find out the power (watts), you will need to look at your washing machine's nameplate, which will indicate both its rated voltage and its rated power.
Why input impedance of FET is higher than ordinary transistor?
the gate is insulated from the channel by either a reverse biased junction or silicon dioxide.
