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 works on the principle of the mutual induction of two coils or the electromagnetic induction of Faraday’s law. When the current in the primary coil … Read more

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 can lead to the burning of the primary winding of the transformer. Means,¬†When a DC voltage is applied to the primary winding of a transformer … Read more
