IN SOME CASES THE TRANSFORMER IS DESIGNED TO APPLY DC
PULSE( NOT CONTINUOUS DC SIGNAL ) TO ITS PRIMARY WINDING
AND THE TRANSFORMER IS CALLED AS "PULSE TRANSFORMER".
IF DC VOLTAGE IS GIVEN TO WDG; AS WDS IS AS GOOD AS
INDUCTOR HENCE CURRENT I=(1/L)*INTEGRAL(Vdc)dt, WHICH WILL
CONTINUOUSLY INCREASE THE CURRENT FLOWING THROUGH THE
WINDING. HENCE THE WIDTH OF THE PULSE SHOULD BE SMALL
OTHERWISE THE TRANSFORMER WINDING WILL BURN.
IN THE PULSE TRANSFORMERS THE RESISTANCE OF THE WINDING
SHOULD BE KEPT MINIMUM TO LINIT THE I^2*R LOSSES AND LIMIT
THE TEMP OF THE WINDING BEFORE INSULATION FAILURE.

In Transformer secondary the emf induced depends on the
rate of change of flux,If square pulse or pulsating DC is
given thn output will be triangular wave(due to inductnce
of secondary)

It depends on the width of pulse,otherwise transformer will
go in saturation.also at secondary the pulse will not be
simple pulse but it will be rather impulse.

Depends on the type of the input given, wheather current or
voltage .
If its a current waveform then considering the changes in
emf on the primary side to the induced emf on the sec side,
it will go phase changes to result the output in the form
of ramp & slope resulting in the triangular waveform.
Considering the voltage waveform we receive output in the
form of impulse waves or square waves with reduced widths.

A car is filled with 4.5 gallons of fuel for a round trip .
Car is taken 1/4 more than in going than coming up. What is
the fuel consumed in coming up ?

There are 2 toy cars facing each other at a distance of 500
cm from each other . Each other moves forward by 100 cm at
a speed of 50 cm/sec and then moves back by 50 cm at a
speed of 25 cm/sec . how long will it take the cars to
collide each other ?

In a certain code, PEAK is written as ?3512? and DINE is
written as ?6895?. How is KIND written in that coade?
(a) 2396
(b) 2986
(c) 2896
(d) 2596
(e) None of these

The total expense of a boarding house are partly fixed and
partly variable with the number of boarders. The charge is
Rs.70 per head when there are 25 boarders and Rs.60 when
there are 50 boarders. Find the charge per head when there
are 100 boarders?

The sum of the digits of a two digit number is 8. When 18
is added to the number, the digits are reversed. Find the
number? pls explanation is important
