trf cannot work on dc. the primary flux must vary for induction to occur in the
secondary winding.

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.
What equipment uses Nlb200050w1a ac adapter?
Transformer Power Supply
What type of voltage must be passed across a transformer?
A transformer must be connected to an alternating current (AC) supply of the correct voltage.
The device that converts AC to DC to run the computer is called?
power supply
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
How many volts does a mini connector have?
Depends on use,supply,AC,DC .Voltage,transformer ???
Why do transformers work only work on an AC supply?
Transformers only work on ac supply because it principle is mutual induction. DC supply has constant magnitude whereas AC has alternating magnitude. so we can step up or step down current/voltage in transformer in ac only.
Why will or won't a transformer operate on AC?
transformer will work on ac
Is the power supply for a Digitech whammy II 9v or 12v I need the specs for the power supply?
whammy 2 specs. ps750 class 2 transformer Ac-Ac power supply input: 120vac 60Hz 12w output 9v AC 780mA
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.
What is the difference between a transformer and a rectifierwhich are found in a PC power supply?
The rectifier is what changes your AC into DC that the computer can use. Transformer raises or lowers the voltage. So you have 110 volts AC coming into your computers power supply. The Rectifier circuit in there changes the AC voltage to DC voltage but it is still to high for the computer use. The transformer lowers that voltage down to the various voltages that your computer needs
