what happen if we give square wave instead of sine wave to the transformer..

Answer / abhishek

the flux changes only when the square wave changes its
value wrt time. this will happen only at edges of the
square wave, and corresponding flux change will give voltage
(spiked one) at the interval decided by time period of
signal. or a series of impulse signal separated will be
generated(at interval T/2) .

Answer / hardik patel

Ya its true that frequency remains same but it will give a
pulse when magnitude of square wave changes. so output can
never be a sine wave or a square wave either.
In short when dI/dt(Chande in magnitude or direction of
current) will be there ... u will find change in output
also.

rather to say dI/dt v can say dQ/dt(change in flux) which
ultimately depends on change in current.

So in square wave flux changes after T/2 period only so at
T/2 interval output will be a pulse only.

Answer / swati agarwal

all peple know tranformer is a static device .it never
change frequency but only amlitude it change.so amplitude
will be change..

Answer / vishvesh bhatt

as we feed alternative power at primary, we get it same at secondary according to winding ratio, but output voltage equation changes, as for sinusoidal wave, form factor is 1.11, for the square wave it is , so, according to that we get output voltage different than we get in sinusoidal wave.

Answer / venu

there should be change in current with time dI/dT then only
flux generates.
