(4 Questions)

  • Q1. What is transformer ?
  • Ans. 

    A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

    • Transformers are used to increase or decrease the voltage of an alternating current (AC) signal.

    • They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.

    • The primary winding receives the electrical energy from the input circuit a...

  • Q2. How to work 3 phase induction motor?
  • Ans. 

    A 3-phase induction motor works by creating a rotating magnetic field that interacts with the rotor to produce motion.

    • A 3-phase induction motor requires a 3-phase power supply.

    • The stator windings create a rotating magnetic field.

    • The rotating magnetic field induces currents in the rotor, which in turn creates a magnetic field.

    • The interaction between the stator and rotor magnetic fields produces torque and rotation.

    • The s...

  • Q3. Which principles transformer are work?
  • Ans. 

    The principles that transformers work on

    • Principle of electromagnetic induction

    • Principle of mutual induction

    • Principle of energy conservation

    • Principle of step-up and step-down voltage transformation

    • Principle of magnetic flux linkage

  • Answered by AI
  • Q4. What are the types of losses in transformer ?
  • Ans. 

    The types of losses in a transformer are copper losses and iron losses.

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

    • Iron losses occur due to the magnetic properties of the transformer core.

    • Copper losses include both the I^2R losses in the windings and eddy current losses.

    • Iron losses include hysteresis losses and eddy current losses in the core.

    • Copper losses can be reduced by using larger conduc...
