What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
Can you step up or step down the DC voltage by a transformer?
You need alternating current for a transformer, for DC you would have to interrupt the power supply to make it effectively DC pulses.
How dc supply is given to transformer used in push pull amplifiers?
The dc is supplied via a centre-tap on the transformer. This ensures zero dc net flux in the transformer core, which enables a much smaller core to be used.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
Why transformer can not be used in dc supply?
The transformer cannot be used in the DC supply because it keeps on alternating its current, whereas the DC supply current should be constant.
Why doesn't transformer work on a DC supply?
to have transformer action there should be an alternating magnetic flux.but dc supply cannot produce alternating flux.
What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
Do pulse transformer is work on dc supply?

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 you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
What will happen if transformer are connected to dc supply?
It will get core saturation
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
