Description : Eddy currents are induced in the pole shoes of a D.C. machine due to?
Answer : Eddy currents are induced in the pole shoes of a D.C. machine due to relative rotation between field and armature.
Description : The transient currents are associated with the?
Answer : The transient currents are associated with the changes in the stored energy in the inductors and capacitors.
Description : List at least two examples that show how static electricity can be generated.
Answer : Examples of how static electricity can be generated include combing your hair, walking across a carpeted room, or sliding two pieces of plastic across each other.
Description : Explain how sinusoidal AC voltage is generated by using simple one loop generator.
Answer : An electric current produced by means of electrical machine is known as generator which converts mechanical energy into electrical energy. When conductor cuts the magnetic flux, emf induced in it. (Faraday' ... upon position of armature. The nature of emf is alternating as shown by the waveform.
Description : How eddy current can be minimized?
