Answer
1
2=(1+1)1
6=(2+1)2
21=(6+1)3
88=(21+1)4
So 445=(88+1)5
& 2676=(445+1)6


Simple logic :-)

Answer
(x*i+i)
1*1+1=2,
2*2+2=6,
6*3+3=21,
21*4+4=88,
88*5+5=445,
445*6+6=2676.

1,2,6,21,88,445,2676.

Question
difference between connection less and wireless network ?
Rank Answer Posted By  
 Question Submitted By :: Srinivas.ece71
I also faced this Question!!   © ALL Interview .com
Answer
if its wireless network then data or information is passed 
through signals and so network is created.but 
connectionless network means its no network orno connection 
between two systems.so its of no meaning.

Answer
because transformer loss depend upon voltage & current

Answer
we know that power=V*I
unit of voltage is volts ,unit of current is amps
so the transformer rating is in kva

Question
Y  Electrical engineerig mainly the supply as sinusoidal 
otherthan non-sinsoidal?
Rank Answer Posted By  
 Question Submitted By :: Kkb2003
This Interview Question Asked @   Infosys
I also faced this Question!!   © ALL Interview .com
Answer
ans
1.
    sinusoidal functions are easy to analysids
2.
any non sinusoidal function can be transformed into 
sinusoidal functions according to FOURIER THEOREM

3. in especially Electrical engineerig  we r using
mainly the supply as sinusoidal otherthan non-sinsoidal
because  all elctrical circuits have only r,L,C as passive 
elements.for finding current in a inductor for a given 
sinusoidal a.c supply we have to calculate through 
integration of sinusoidal input which gives again as 
sinusoidal.however, with some phase isplacement.Simmillarly 
for capaxcitor also to find current from sinusoidal input 
voltage we require differentiaton, which gives again as 
sinusoidal.however with some phase displacement

Answer
1.Sinusodial signals have only one freq component which is 
its fundamental freq.Every system's gain is calculated with 
reference to sine signal only.THE reason being every system 
is bound to have a finite bandwidth and if use other 
signals like square for calculation of gain ,it would give 
errorneous rersults, as squre has infinite freq comp and 
higher freq comp will not be allowed(Due to finite bw of 
s/m).
Hence as gain is wrt to sine then it makes sense to use
sine signal only.

2.It doesn't hav dc comp and hence helps in coupling with 
transformers.
