before some 100 years ago itself they began to argue with
this, it was the "WAR OF CURRENTS"(whether to use AC or DC)
that is between tesla and edison, edison came with DC and
tesla came with AC,
finally tesla proved that AC is more powerful by introducing
a electric chair made of AC, since then AC power is applied
for Electric chairs..,and thereby we are now almost using AC
everywhere. if AC is used to kill people, imagine a
defibrillator used when a man about to die, giving a
electric shock he can be made alive, for that electric shock
DC is applied.
AC or DC, its the amount of current passes through u, AC
first causes a muscular contraction, DC first causes,
electrolysis of blood..,

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
