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 is a DC generator the same as?
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
Can AC motor work on DC?
use a inverter to change dc to ac or couple it to a ac motor making it a motor generator. Comment: AC motors cannot run on DC since their principle of operation based on induction. There's an exception,however, and thats for Universal Series motor which can run on either AC or DC.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Is induction voltage ac or dc current?
Induction occurs only with alternating current.
Why transformer supply is ac?
trf cannot work on dc. the primary flux must vary for induction to occur in the secondary winding. howlunf
Why you have to connect DC supply to the induction motor?
To start an induction motor we have to excite field. The excitation is done by connecting the DC supply to the field winding's.

What will happen if inductor connected with DC supply?
i think in case of dc supply there will not be any induction

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.
Why DC cannot be stepped down?
DC cannot be easily stepped down using a transformer like AC because transformers work on the principle of electromagnetic induction, which requires a changing magnetic field to induce a current in the secondary coil. Since DC has a constant magnetic field, it cannot induce a current in the secondary coil of a transformer. However, DC can be stepped down using other methods such as voltage divider circuits or chopper circuits.
What is the principles of DC machines?
All DC machines are works based on the principle of FARADAY'S LAW OF ELECTROMAGNETIC INDUCTION.
What kinds of motors can work as generators?
Several types of motors can work as generators, including induction motors, synchronous motors, and DC motors. When mechanically driven, these motors can produce electricity through electromagnetic induction by converting mechanical energy into electrical energy.
