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.

Who is more efficient dc motor or ac motor and why?
DC motors are generally more efficient than AC motors. DC motors have a lower amount of inertial associated with them, making them more efficient to run.
What is the difference between AC and DC average rms and peak values?
RMS minus ripple current , that is alternating current (sinusoidal wave form )it is including ripple voltage and ripple current . peak current is maximum peak in sinusoidal wave form . general used in choke (filter ) design calculation .
AnswerHow do you compare the 'speed' of a circular saw with that of a reciprocating saw? One spins, while the other goes up and down. The answer is that you compare them, not in terms of their individual speeds, but in terms of their 'cutting speeds' (i.e. how fast they cut board).
We do the same thing with a.c. and d.c. We compare one with the other in terms of the 'work' they do. So, for example, a 10-A (r.m.s.) a.c current will do precisely the same amount of work as a 10-A d.c. current.
So the r.m.s. value of an a.c. current is exactly equivalent to the value of a d.c. current that will achieve the same amount of work. Because voltage is proportional to current, the r.m.s. value of an a.c. voltage and a d.c. voltage are also equivalent to each other.
For a sinusoidal a.c. current or voltage, the r.m.s. value is 0.707 times the peak value.
Where can a transistor be found?
Seriously? In just about anything electronic, in one form or another.
How do ions in metal wires resist the flow of electrons?
dunno its a mystery lad go brush ya teeth lol x
What device used to increase or decrease DC voltage?
A DC-to-DC converter is the general term for a device that changes DC voltage at one level to another.
What is meant by electronics and communication?
electronics & communication means receving and sending information through signals
that would be good for the cold idle and should drop three times as the car warms up and should idle about 650 to 800 auto trans
How do you charge a capacitor?
You charge a capacitor by placing DC voltage across its terminal leads. Make sure when using a polarized capacitor to place positive voltage across the positive lead (the longer lead) and negative voltage across the negative lead.
Also make sure that the voltage you charge the capacitor to doesn't exceeds its voltage rating.
i dnt know wats the answer
Do 2 input nor gates form a complete set of logic gates?
nor as well as nand gate
are universal gates they both can be used
as a complete set of logic gates
How do you repair a 680 microfarad capacitor?
To repair a 680 microfarad capacitor, buy a new one and install it in place of the old one. It is unrealistic to attempt repair of a capacitor.
How does the non inverting amplifier differs from voltage follower circuit?
altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.
Why d flip flop called as delay flip flop?
"D" in D flip flop stands for "delay". It basically means that the "D" value is not read immediately, but only at the next positive clock edge.
How is electrical contacts installed on an MS connectors?
Normally, wires are connected to MS connectors via soldering [on aircraft as far as I know, although I am trying to find out about other methods].
Can you use a 9.6 volt battery instead of 7.2 in toy car?
You could, however you may damage the electrical components in the car. The motor, wiring, speed controls etc. are all engineered to operate at the specified voltage. If you want to go faster for a short period of time the higher voltage will do that for you.
a personof vision is someone who has an idea to help many people and works on it making it a reality
Can you use two horizontal amplifier and one one vertical amplifier in dual beam CRO?
I think you'd want just the opposite. The sweep rate is the same for both
beams, so you only need one set of horizontal deflection components. But
the vertical amplitudes of the two signals are generally different at the same
instant of time, and you want to keep the two signals separate and distinct,
so you want them running through two different vertical amplifiers.
Pink noise is noise in which the spectrum density is proportional to inverse of the frequency. It is also known as 1/f noise.

Why the light circuit is separated from the power circuit?
depending on the size of the house you could end up with needing a huge fuse. so it's a logical split. you could have each room separate if you wanted or every single switch. you'd just need a huge fuse board.
also having the lights and power separate means that if one goes then you have the other to provide light.
not really any other reason than the fuse one really.
Q = CV,
Q is charge,
C is capacitance,
V is voltage.
C= Q/V
= dQ/dV since it is linear function
