Transformers depend on fluctuating magnetic fields in order to operate. The operating principle of an inductor, of which a transformer is an example, is to resist a change in current by back EMF which bucks the change (up or down) in current. If you place DC across an inductor, the current would linearly increase until the resistive limit is reached, the power supply's capacity is reached, and/or the inductor self destructs from overcurrent.
What else can I help you with?
What happens when an ac motor is given dc supply?
it burns thats it
What happens if an ac supply is given to dc generator?
AC supplies are not given to DC gennies. A DC gen requires a mechanical prime mover.
What happens if a dc supply is given to a transformer under no load?
when dc supply is given to transformer at primary winding , the output at secondary winding will be zero.Because to induce voltage ,countnie changing flux is required ,that can not be obtained from dc supply...........
Can tranformer covert ac to DC?
no
What will happen when DC supply is given to a bulb?
When a 230 V dc supply is given to a bulb it will glow, because it has just a coil inside.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
What will happen of you give AC supply to stator winding of DC generator?
why the supply is given to the stator of dc generator give answer
What supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
What happens when you pass a 230V ac supply to a man and what happens when you pass 230V dc supply to a man?
He dies.
Ac and dc load line of BJT-explain?
when the dc supply given, dc load line lies in the Ic and Vcc. when the AC supply given, AC load line lies in the Ic and Vcc.
What happens if a DC motor is connected to an AC supply?
Through loda
What will happen if dc supply is given to shunt dc motor?
It will drawn a large amount of current which can destroy the shunt
