Homework Statement I studied that as the single phase motor speeds up the backward induced field currents are larger than the forward field currents. So , the corresponding opposing rotor mmf causes backward field to be greatly reduced whereas the smaller forward currents leads to enhancement...

Homework Statement I studied that a larger air gap in alternators aids in sinusoidal mmf distribution ..I didn't get this as larger air gap should deteriorate the wave..but here it is opposite..?? Is it right ?? [/B]Homework EquationsThe Attempt at a Solution One point can be said that larger...

this doesn't answer my q. I was asking about if synchronous generator have residual magnetism?

Homework Statement Is there no residual magnetism in case of synchronous machines? Actually I had this doubt because of the OCC of alternator as when the field current is zero the generated value of the machine is also zero unlike the dc machines..why is it so?? Homework EquationsThe Attempt...

Homework Statement See , in the methods of improving the commtuation , one of the method is using interpoles now what I think that interpoles aids commutation by nullifying the reactance voltage in the conductors. Though this point is mentioned with the working but it is also mentioned that...

Well.. Its written in India..

Homework Statement What is meant by the term tapping in power system , I studied in my textbook that generally from feeders no tapping is taken to the consumers , therefore current loading of feeder remains the same along its length. I was not getting what is being referred here ..?Homework...

Homework Statement The input bits 0 and 1 are represented by 0 volts and 5 volts respectively. The OP-AMP is ideal, but all the resistances and the 5 volts inputs have a tolerance o f ± 10%. The specification (rounded to the nearest multiple of 5%) for the tolerance of the DAC is?? In this...

it'll be 9...

that's the problem actually I tried this thing..if we see as a whole all and all base 6 suits it..b it will be better if you just have a look..I answered his question... And by the way ..the doubt is clear by now to me...

sorry its 5+4 .. these are the LSBs of the given problem..!

the base will be any number greater than 5..!

How to try the possibilities ..?? what I am seeing your answer is to compare both sides ..is it so??

see about that radix number system , I have done with the conventional method as I stated in my question..but in the short method the picture is different ..if 5+5 =4 and we are getting 3 for base x in the result , how to take the possibilities that's the problem..!

Yes I am quite familiar with it.. and I have solved it accordingly but about the short method I am confused..
