When a square wave is applied to primary of a transformer
then what will be output wave form of secondary ?
Answer Posted / devang
when flux change the voltage induced on secondary side so
we can not use the transformer as dc value step-up-down so
for constant value of square the output zero but the
transformer has the storage energy so the enery decrease
with time constant for high value of time constant the
square value possible but less value of time constant the
squre value not possible
