DC GENERATOR - Practice Mode

1) Which rule is used to find the direction of induced emf in D.C generator?

Cork screw rule Right hand palm rule Fleming's left-hand rule Fleming's right-hand rule

Correct Answer: Fleming's right-hand rule

Explanation:

Fleming's right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator's windings.

2) Which energy is converted into electrical energy by generator?

Heat Kinetic Chemical Mechanical

Correct Answer: Mechanical

3) What is the principle of D.C generator?

Cork screw rule Fleming's left-hand rule Fleming's right hand rule Faradays laws of electromagnetic induction

Correct Answer: Faradays laws of electromagnetic induction

4) Which rule is used to find direction of magnetic field?

Cork screw rule Right hand palm rule Fleming's left hand rule Fleming's right hand rule

Correct Answer: Fleming's right hand rule

5) How many parallel paths in duplex lap winding of a 4 pole DC generator?

4 6 8 12

Correct Answer: 8
