by using step-up transformer we can change the voltage in higher level
All transformers are a.c. machines.
No. Transformers work in AC systems, not in DC systems.
on the basis of field excitation, dc generators are classified into the following types:-1- separetly excited dc generators2-self excited dc generatorsthe behaviour of a dc generator on load depends upon the method of field excitation adopted
Transformers don't work with DC supplies - they only work on AC.
there are 2 different types f excitation 1 seperately excited 2 self excited
It is doubly excited if it is sparately excited dc motor, singly excited if it is self excited machine
There are two types me dc generator 1 separately excited dc generator 2 self excited dc generator
No, unless you have a pulsating DC
All transformers are a.c. machines.
Transformers are not used on DC circuits because they rely on a varying magnetic field to transform power.
I know that they made Transformers Revenge Of The Fallen in Egypt and in Washington DC.
These devices are not transformers, but toroid hall effect sensors. That is how they can sense DC.
No. Transformers only work with AC. Tongue-voltage is DC.
The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
The DC output will be zero because transformers do not operate on DC there would be a slight peak when switched but then it would settle to zero. Transformers require a changing magnetic field to transfer power.
