Question # 1

Define mutual inductance and write at least two factors at which it depends.

  • Ans 1: The ratio of average emf induced in the secondary to the time rate of changing current in the primary is called mutual inductance.
    It depends upon numbers of turn of the coil,area of cross section of the coil closeness of coil and nature of the core materials.

Question # 1

Can DC motor be turned into DC generator?What changes are required to be done?

  • Ans 1: Yes ,a D.C motor can be converted into D.C generator.For this armature of the motor is to be coupled with some rotating body.Due to rotation ,magnetic flux through the coil changes so and emf will be induced at the output.Hence the motor acts as a generator.
