Answer / yogan

Because of no change in direction and magnitude of the wave
form. so no flux linkage in the secondary coil. Instead
primary coil will burn due to no load impedance.

Answer / tarun aggarwal

transformer work on principle of induction,that changing flux
which occur in a.c supply while in dc magnetic flux doesnot
change so no induction occur in secondary

Answer / rinku kumar

Transformer cannot work on dc supply because dc voltage has
no frequency when we give dc voltage to primary winding
then will not produce e.m.f. and so low resistance cause
high current flow in the primary winding and finally
winding will burn.

Answer / jain

for mutual induction the alternating flux is needed. Dc
cannot produce alternating flux. so the transformer cannot
work with dc

Answer / kapil bahadure

transformer work on principle of induction,that changing
flux which occur in a.c supply.
dc magnetic flux of pramary winding not cut with secondory
winding by air gap.
Transformer cannot work on dc supply because dc voltage has
no frequency when we give dc voltage to primary winding
then will not produce e.m.f. and so low resistance cause
high current flow in the primary winding and finally
winding will burn.

Answer / kapil narayanrao bahadure

Transformer works on the principal of mutual
induction.Transformer cannot work on dc supply because dc
voltage has no frequency. when dc supply give to
transformer then dont produced alternating magnetic flux &
also not cut to secondory winding.by air gap.

Answer / deltawye

transformer not work in dc,it is simply because transformer
deal with frequency,while in dc Freq=0,it will only damage
your transfomer due to low resitnc...

Answer / nadeem ahmad

in simple language, we can say that there is no change in
flux in dc so the x'mer can not work on dc but it can be
opereted on dc if we cange the polarity very fast by any
how.

Answer / dpoo77

Transformer works on the principal of mutual induction
just becouse of rate of change of flux n it happence due to
AC it is not possible in DC

Answer / eknath

no fequency in d.c. so that transformer would be burn.

For an 100kw generator, only 50kw of load is connected. Will the generator generate only 50kw or 100kw. If it generate 100kw what happens to rest of the 50kw. What happens if we connect more than 100kw of load?

why battery dc voltage become Half when we check with respect to ground for example 120volts + and - terminals and when we check + terminal with Earth thats 60volts why 60volts same result on 24Volts and with ground 12Volts only expert answer that thanks we can not ground the battery.

I am having a 42KW 3 phase electrical heating furnace, heating element is 80/20 nichrome material, my connections is made in such a way that 2 star connection compromising 2 coils per phase so totally 12 coils, shall if i use it unbalanced star condition (instead of 2 group of 3 phase or 1 group of 3 phase, connecting 4 phases of 5 phases) what will be the consequences and is it acceptable?
