Why Transformer is not Connected to DC Source | What will happen if Transformer is connected with DC

The transformer is a device which transfer electrical energy from one circuit to another without changing the frequency by the principle electromagnetic induction. The transformer has two windings primary winding and secondary winding. These two windings are connected by a common magnetic circuit.The transformer operates only in AC source. There are two main reasons why transformer works on AC…

Difference between Self induced & Mutually induced emf

If an emf is induced without moving either the conductor or the flux, such an In transformers and reactors static emf is induced emf is called statically induced emf. This is classified into two types.1) Self induced emf ( Current changes in the coil itself ) 2) Mutually induced emf ( Action of neighbouring coil )

Self Induced EMF :

It is defined as the emf induced in the coil due to increase or…
