  • Q1. Basic law of governing transformer
  • Ans. 

    The basic law governing transformers is the law of electromagnetic induction.

    • The law states that when the magnetic field around a conductor changes, an electromotive force (EMF) is induced in the conductor.

    • This EMF can cause a current to flow if the conductor forms a closed loop.

    • In a transformer, this principle is used to transfer electrical energy from one circuit to another through electromagnetic induction.

    • The prima...

  • Q2. What are various losses in transformer
  • Ans. 

    Various losses in a transformer include copper losses, iron losses, and stray losses.

    • Copper losses occur due to resistance in the transformer windings.

    • Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.

    • Stray losses occur due to leakage flux and stray capacitance in the transformer.

    • Copper losses and iron losses are the major contributors to total losses in a transfo...
