Difference between silicon-controlled rectifier and diode?
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
What is the difference between npn and pnp transistor?
In NPN transistor, Base is connected to positive terminal of battery.Now, when current is switched on, Base-Emitter junction (indicated in image) is forward biased, whereas Base-Collector junction is reverse biased.Remember that forward bias narrows depletion region, whereas reverse bias widens depletion region.n-type region(lower one) on emitter side has majority electrons (reason 'n' stands for negative).These electrons move from emitter side to base.Base is thin region, which has holes. When electrons move from emitter to base only a few electrons combine with holes. Whereas others pass from base to collector.In collector the electrons are pulled by positive terminal of battery(right hand side battery). And thus the cycle of current continues to flow.That is whole working of NPN transistor.
What happens if one leg in a 3 phase synchronous motor fails does it reverse its rotation?
No it does not reverse rotation. If the proper motor protection is used on the motor, the motor should trip off line. Loosing a leg will drive the other two legs of the motor into a higher than normal state. This higher current will be sensed by the overload protection and the motor contactor will drop out. This opening of the motor contactor will drop the supply to the motor and the motor will stop.To reverse a three phase motor, reverse any two feed wires to the motor. This is usually done at the motor's junction box to preserve the wire colour coding of the wires through out the system.AnswerDo you really mean a 'phase' or do you mean a 'line'? This is an example of where the use of correct terminology is important. 'Losing a phase' means losing one of the machine's three field windings, whereas 'losing a line' means losing one of the three supply conductors. Two completely different situations for a delta-connected machine.For example, for delta-connected field windings, the three-phase supply is maintained and the machine assumes an 'open delta' condition, whereas losing a line places two windings in series and in parallel with the third, across a single-phase supply.
What is the difference between program and process?
Program is a set of instruction whereas process is program in execution. Program is passive entity whereas process is active entity .Program has single instance whereas process has several instances.For eg.several notepad windows can be opened but same program is executed behind each window. Program is dependent on logic used whereas process is dependent on program.
What are the advantages of using concrete instead of these traditional building materials?
wood: wood can crack unlike concrete and wood is affected by water which can cause it to rot whereas concrete is not Metals: Metals can rust whereas concrete does not and metals can easily scratch Bricks: Bricks are more expensive than concrete and bricks take generally more 'man power' to place down whereas concrete does not. Hope this has been a good help
What effect of depletion layer by biasing?
on forward biasing width of the depletion layer decreases whereas on reverse biasing the width of depletion layer increases.
What is the no ip domain lookup command used for?
Ip domain lookup command used for forward lookup and reverse lookup to be done in router.to resolve name to ip - forward look up and ip to name - reverse look up.. Router is responsiblr for the same hence we configure this cmd in router whereas switch is not responsible for dns lookup hence at the time of switch configuration we disable this cmd with "no ip dns look up".....
Is it forward to Sam and me or Sam and I?
"It is forward to Sam and me" would be correct. Use "me" when it is the object of the sentence, whereas "I" is used when it's the subject.
Do you have a sentence with the word whereas?
Many people had told us it was expensive to buy things through a courier, whereas I had supposed it was just the reverse.
What is the difference between the two cavity klystron amplifier and reflex klystron?
klystron can act as both an amplifier and oscillator whereas a reflex klystron can act as only an oscillator. klystron needs a buncher cavity(sometimes multiple bunchers) and a catcher cavity whereas a reflex klystron needs only one cavity. klystron bunches electrons in forward direction, whereas the other bunches in the reverse direction using a reflector plate. klystron needs i/p signal (accelerating or deccelerating potential) whereas the other dont.
Difference between normal fault and reverse fault?
The movement of the Hanging wall in the normal fault downward with the gravity whereas in the Reverse fault the hanging wall moved upward against the gravity
Forward contracts are traded in a competitive arena whereas futures contract may be traded by telephone or telex?
false
MK2 how to do red shadow kick with Johnny cage?
Back, Back, Forward, Low Kick (or LK for short). Whereas his Green Shadow Kick is Back, Forward, Low Kick.
How are hypertonic solution and hypo tonic Solution related?
A hypertonic solution has the solute greater than the solvent, whereas a hypotonic solution is the reverse.
Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
Why are recitative and an aria are musical opposites?
Recitative is used for regular dialogue and moving the plot forward in opera whereas aria is used for expressing the particular emotions of one character in an elaborate way. In arias the plot does not move forward.
Why cant routers forward packets as fast as bridges can?
It is a fact that bridges forward packets faster when compared to routers. Because router takes time to find the shortest path between source and destination,whereas bridges directly forwards the packets.
