Yes.
Yes, you can replace a transformer with one that has a higher current rating. The load on the transformer should be less than 200mA because presumably that is what the circuit was designed for. Since the current through the transformer should be less than 200mA, the 500mA transformer will not be damaged. The opposite is not true. You should not replace a 200mA rated transformer with a 100mA transformer, for example. If the current exceeds 100mA, the transformer could fry.
What else can I help you with?
What must be the rms voltage rating of the transformer secondary for the voltage doubler that produces an output of 500 v?
The transformer should provide 144-0-144 v to have a no-load voltage of 500 v dc in a voltage-doubler using two diodes.
How does a DC transformer work?
transformer cannot be worked on DC because as the dc is constant there will be no change of flux & may lead to shot circuit.
Who will not operate on DC?
Transformer
How do you make ac into DC in a ac transformer?
You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater
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 .
If DC is applied to the primary of a transformer is there any current in the secondary and if there is then whether ac or DC?
first, understand that a transformer is an AC DEVICE. it wont work on dc...
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.
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 the windings burn when transformer is operated in DC?
Transformers are not intended to be operated in DC. DC does not provide the continuously fluctuating current that a transformer requires in order to function. On DC, a transformer will act as a transient mode inductor, and settle out to a high current state, destroying itself.
Why transformer do not operate with DC?
Transformer works with varying flux. DC won't create it. Only AC produce varying flux.
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.
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.
