What else can I help you with?
How do you reduce a 230v ac transformer to produce 140v ac?
By using step-down transformer
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 dc supply is applied to field coil in a brush less alternator?
Through a coupled inductor, similar to a transformer, but working on DC instead of AC.
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What type of electrical equipment cannot convert AC into DC?
A transformer cannot convert AC into DC.
Why will or won't a transformer operate on AC?
transformer will work on ac
How are is a transformer and a rectifier different?
A transformer changes the VOLTAGE of AC current (AC to AC). A rectifier changes AC to DC.
How do you reduce a 230v ac transformer to produce 140v ac?
By using step-down transformer
What is the Name of the transformer in which the output AC voltage is less than the input AC voltage?
It is a step-down 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
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
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.
Can transformer operate on triangular wave DC?
If its a triangular wave, its not DC, its AC, its just not sinusoidal. Can a transformer operate on triangular AC? Yes, but not as efficiently as on sinusoidal AC.
Can you amplify the AC in your data center using an AC transformer and how?
Yes, the AC current can be amplified by using Step-down transformers, but one problem is the AC voltage will decrease with Step-down transformer.
Which type of current does a transformer work with?
A transformer works with alternating current (AC). The primary coil of the transformer is connected to an AC power source, which creates a changing magnetic field that induces a voltage in the secondary coil.
How dc supply is applied to field coil in a brush less alternator?
Through a coupled inductor, similar to a transformer, but working on DC instead of AC.
How can you step down 220v ac to 150v ac?
By using a Variac Transformer
