how do transformers work

The transformer is a static device that converts electrical energy from one circuit to another without changing its frequency. it raises (or decreases) the voltage and current level. The transformer…

What will happen if a DC voltage is given to the transformer primary?

When DC power is supplied to the primary transformer, no self-induced EMF is generated (no back EMF). Therefore, in the primary winding of the transformer flows a strong current, which…
