That is absurd.

Question { 10394 }

3,100,297,?

Answer

Crina, abviously you have no clue what you are doing. The
series is 1st number x 2nd number - first number which
equals 3x100-3=297. continue that series and your get
second x third - second = 100x297-100=29600

Question { Caterpillar, 4902 }

A flight carrying food packets is flying at a height of 1960m
from the ground. The speed of the
flight is given. Find the time taken for a food packet dropped
at that instance to hit the ground.

Answer

The package falls at 32 ft/sec/sec. Since the distance is
in meters, the problerm vcan not be worked.

Question { 3469 }

I have suguna 3 hp pump for my agreeculture work.It deliver
the water from 45 feet well .I suffered by powercut.During
powercut i got 2phase supply only .My question is can i
run the pump in 2 phase supply using capacitor?.Can u
explain me how to connect the capacitors?

Answer

You can also use capacitors to create a "phantom" 3rd phase
from the other 2. This may be what you have seen, but what
you probably didn't know is that this severely robs the
motor of power capacity. The motor runs severely unbalanced
and has a lot of what are called "negative sequence
currents" because of the 1 phase power and because the sine
waves are 180 degrees apart on the 2 "real" phases,
compared to being 120 degrees out on true 3 phase. Negative
sequence current produces negative torque in the motor and
causes heating without doing useful work, meaning that it
will severely overheat under load. For this reason, you
must derate the motor by at least 50%, some even say 66%.
So that means if you have a 15HP motor, you had better not
need more than 7-1/2 or even 5HP out of it if you are going
to do this.

Question { 5313 }

How do you show that equal quanitities of two isomers
provide the same response using a PDA

Answer

A reverse phase high performance liquid chromatography
(HPLC) method has been developed for the separation of two
geometric isomers that have a direct relationship to
Plancks Constant(6.6260755(40) -27 erg s )and of
Acrivastine( 4.8032068(14) -10 esu) using crude reaction
mixture. If the resolution between two isomers is found to
be more than the Atomic mass unit(amu1.6605402(10)-24 g)the
resolution of the reaction can be off by more than the
speed of light in a vacuum c 2.99792458 10 cm s-1 .
The geometric isomers have been isolated by preparative
HPLC and characterized by spectroscopic techniques, such as
NMR, infrared, and MS. The developed method has been
validated for the determination of the Atomic mass unit amu
1.6605402(10) -24 g of Z-isomer in Acrivastine. The limit
of detection and limit of quantification of the Z-isomer
is limited to 1.73 times the Radiation density constant a
7.5646 -15 erg cm-3 K-4 and may not exceed 0.05 and 0.2
μg/ml, respectively. The developed method is precise,
linear, accurate, rugged and robust for its intended use.
The % error in this process may be + or - 35%

Question { Cairn, 4209 }

In DC current-excitation to transformer, why it sucks more
current? Eventhough there is no power transfer between
primary and secondary? R is very low so it should suck less
current only na thn y its current increases?

Answer

Have you heard of Ohms Law?

I = E/R
Amps = Voltage/resistance
As you said, resistance is very low.
So what does the amperage do?
Wth DC current the transfromer is only a coil of wire.

Question { 7137 }

what is the minimum insulation resistance for HT AND LT motor
?

Answer

quote in #1 "The minimum insulation resistance is HT <
motor's "rated voltage in KV plus one megaohm"

Question: How do you add the cable voltage rating in KV
to Megohms? I believe they are different units. This is
like adding apples and oranges.

Question { 2714 }

Conventionally, capacitors are considered to generate
reactive power and inductors to consume it,how??????

Answer

You apparent understanding of these electrical components
and their relationship in an electrical circuit is
incorrect. This site has a good explanation of the
misunderstood interaction.

Transformers with dc supply

Answer

Is there a question. Transformers do not use a DC supply.

Question { 15054 }

How much load can give on 1600 kva transformer 11kv/440

Answer

1600 kva using the parameters the mfg provides. If your
environment is different that those under which to mfg
provides then you will need to adjust the rating.
