Question # 1

Write down any one method used for the production of induced emf.

  • Ans 1: Induced emf can be induced by electromagnetic induction.When a conductor is moved through a magnetic field the electric current flow through the circuit,The emf produced in the conductor is called induced emf and the current generated is called induced current.

Question # 1

How can the power losses be minimized in a transformer?

  • Ans 1: The power can be minimized in transformer by implementing following considerations.
    1. Core should be assembled from the laminated sheet of a material whose hysteresis loop are is very small.
    2. The insulation between lamination sheets should be perfect so as to stop the flow of eddy current.
    3. The resistance of the primary and secondary coils should be kept minimum.

Question # 1

What is back emf in motors?

  • Ans 1: When to coil motor rotates across the magnetic field by the applied potential difference V,an emf is induced in it.The induced emf is in such a direction that opposes the emf running motor.Due to this reasons,the induced emf is called back emf of the motor.The magnitude of the back emf increase with the speed of motor.
