Explain the working of master-slave JK flip flop?
A: A JK flip flop is called that since it has conditional inputs as J and K. For it to toggle many inputs must be present at the same time. It also can toggle during the rise or fall of the clock or state of the clock There are too many JK flip flops and their function to cover it all and explain the functions. For a design engineer it can choose any to do the work.
What law is used to find the polarity of resistor when two voltage source are connected?
Hi!
Well, it depends what voltage is "pushing" harder on the resistor. If you are ONLY dealing with 2 voltage sources and a single resistor, then the voltage source with the higher potential (or voltage) will dictate what polarity the resistor is.
Cheers!
How does computing valve work?
Just like the valves used in valve stereo equipment or old radios.
Except in computers (like the transistors in modern computers) valves are usually driven fully into saturation and cutoff, while in a valve stereo or old radio valves are usually operated as linear amplifiers with minimal distortion.
Resistors (R) in series are added by... Req = R1 + R2 + R3 + ... + Rn
In parallel... 1/Req = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn
or Req = 1/(1/R1 + 1/R2 + 1/R3 + ... + 1/Rn)
Can you use 8 ohm speakers on a 10 ohm radio?
Never haerd of a 10 ohm radio. There is no 10 ohm radio amplifier on the market, when you think that must be the output impedance of the amplifier. The output impedance of a radio amp is always less than 0.5 ohms. Scroll down to related links and go to "Voltage Bridging or impedance bridging - Zout < Zin"
How many squares does a karnaugh map require for a three-variable boolean equation?
8, as you have 2^3 possibilities.
If you depict it in three dimensions, you have a cube of 2x2x2 = 8. However, this isn't useful to most people who find Karnaugh maps useful. To keep it two dimensional, we usually combine two of the variables. For example, if the variables were A, B, and C, one would write a 2x4 grid with A and A' (NOT A) on one axis, and BC, BC', B'C, B'C' on the other.
Can you ruin a television by setting a magnet on it?
Yes that's right, he tried. The colours fade and everything goes all crap xD
P.S: Kids, don't try it at home D=
TV are electron emission from a cathode to the plate. Any magnetic flux can effect it. Actually to insure purity at turn on an AC flux is brought on the TV to insure no residual magnetics removal. This particular TV can be possibly be restored if A VERY STRONG AC magnet is slowly removed therefore removing the flux.
What are the steps performed by Demorgan's theorem?
DeMorgan's theorem can be simply be stated simply as "Break the line, and change the sign." Where line represents complement...
Although I would not recommend it, yes you can as most are non-toxic.
If however you meant elemental Phosphorus instead of phosphors, NO, some form of Phosphorus are deadly poisons and white Phosphorus spontaneously ignites on contact with air!!!
If you don't know the difference between phosphors and Phosphorus, that is the subject of a different question.
Is oit possible to use three input in ic 7486?
If you look at the 7486 IC datasheet you can see, it have 4 independence XOR gates with 2 inputs. So you can only use 2 inputs if you see it like that.
But if you understand the truth table of XOR gate you can have 3 input application using 7486 IC. Here I will show you how.
1.Get the first 2 input into the first XOR gate.
2.Then get the 3rd input together with the Output from the first 2 input XOR gate into another gate.
3.This output should be the result of 3 input XOR gate.
Check this output with 3 input truth table to confirm the answer.
What is average value in alternate voltage?
The term is 'alternating voltage', not 'alternate voltage'. For an a.c. voltage or current, the average value is taken over half its wavelength because, over a complete wavelength it is, of course, zero. For a sine wave, the average value (over half a wavelength) is 0.637 Vmax or 0.637 Imax.

How do you set up a megger to test insulation resistance on self regulating heat tracing?
One lead will go on the braided shield (this is essentially the ground), the other lead goes on the heating conductors. Megger either one lead at a time, or both conductors under the same lead. I usually test at 1000v - follow manufacture's spec if unsure.
You cannot test line to line with a megger. Testing line to line with an ohmmeter is of some use, as the ohmic value will be dependent on the length, wattage and, to some degree, the temperature of the heat trace. This test is most useful with more than one run of identical heat trace, or to track one piece over time. Values far outside of what is expected will indicate damaged (open or shorted) heat trace.
Why open loop control system is difficult to handle?
its no different than weather forecasting
if the temperature pressure, loading, rpm, viscosity, input, output, and load conditions remain the same open loop is just set and forget
if you flip the light switch the light comes on, no need to confirm that the light is on before walking down the stairs

What is the process called in which a conductor cuts across a magnetic field and produces a voltage?
We call it induction when we pass a conductor through a magnetic field to produce voltage.
Five 60 ohm resistors are connected in parallel What is their equivalent resistance?
1/R = 1/60 + 1/60+ 1/60+ 1/60 + 1/60
1/R = 5 / 60
R = 60/5
R = 12 ohms.

"What are the undesirable and unwanted effects in the medium?
What does a rapid change of a magnetic field induce?
It does not have to be positive or negative either one will produce reversal of the voltage applied by a factor
