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.
Depends on the type of the input given, wheather current or
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.

Potatoes are made up of 99% water and 1% “potato matter.”
Jack bought 100 pounds of potatoes and left them outside in
the sun for a while. When he returned, he discovered that
the potatoes had dehydrated and were now only made up of 98%
water. How much did the potatoes now weigh?
In a sports contest there were m medals awarded on n
successive days (n > 1).
1. On the first day 1 medal and 1/7 of the remaining
m - 1 medals were awarded.
2. On the second day 2 medals and 1/7 of the now
remaining medals was awarded; and so on.
3. On the nth and last day, the remaining n medals
How many days did the contest last, and how many medals
were awarded altogether?
