Yes. Transformers operate on the theory of inducing current in one coil by starting and stopping the current in another coil on the same iron core. The voltage changes as a function of the turns ratio of the primary (driven) side to the secondary (output) side. Alternating current changes rapidly each second (e.g., 50, 60 400 Hz). To use a transformer in DC-to-DC converters, you first need to create a wave, run it through the transformer to get the new voltage, then rectify and filter it to restore the output to a DC voltage. Is this a trick question? AC in and AC out. Straight DC won't work without help. The DC is "switched" or "chopped" or "turned on and off" quickly in the primary, and this action will allow the pulsating DC in the primary to drive the secondary of the transformer. Problem solved.

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.


How does auto transformer work with DC supply?

Transformers don't work with DC supplies - they only work on AC.


Transformer are used in circuits containing both dc and ac?

No transformers only work with AC.


Can you harness the 1 100th volts that comes from your tongue using transformers and a dc to ac converter?

No. Transformers only work with AC. Tongue-voltage is DC.


Can you harness the 1 100th of a volt that comes from your tongue using transformers?

No. Transformers only work with AC. Tongue-voltage is DC.


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.


Which is used in South African electricity supply network ac or dc why?

AC is preferred in distribution due to the economy, efficiency, and reliability of transformers.


Does the battery method have any limitations on testing the transformers polarity?

yes its does the higher the current will blow out the transformers


When ac motor is connected with DC supply?

Basically AC motors would not work on DC supply but there's however an exception for a Universal motor also known as a series motor. This is the only motor as far as I know that work on both AC and DC.


What is a set down transformer?

A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.


Is it appropriate to use dc supply in a transformer?

Not usually. Transformers require a varying magnetic field, which is induced by AC voltage.


Why alternating current is use for electrical system?

The transmission of electrical energy requires very high voltages (for a given load, the higher the supply voltage, the lower the load current). To increase/reduce these voltages, you need transformers. Transformers are AC machines; they do not work with DC.
