Sample EE6352 Electrical Engineering and Instrumentation Important questions
1. How will you find the direction of emf using Fleming’s Right Hand Rule?
The thumb, the forefinger and the middle finger of the right hand are held so that these fingers are mutually perpendicular, then Forefinger – Field Thumb – Motion Middle finger- I, current
2. How will you find the direction of force produced using Fleming’s Left Hand
Rule?
The thumb , forefinger and middle finger of the left hand are held so that those fingers are mutually perpendicular then Forefinger – Field Thumb – Motion(due to force) Middle finger – I, current (ee6352 electrical engineering and instrumentation Important questions)
3. How are armature windings classified based on the placement of the coil inside the armature slots?
Single layer winding and Double layer winding
4. Write down the emf equation for d.c generator.
E = (фNZ / 60)(P/A) V Where P= number of poles Z= Total number of conductors
A= number of parallel paths Ф= flux per pole N= speed in rpm
5. Why the armature core in d.c machines is constructed with laminated steel sheets instead of solid steel steel?
Steel sheets offer low relutance path for the magnetic field , laminated sheets reduce eddy current loss. (ee6352 electrical engineering and instrumentation Important questions)
6. Why is commutator employed in d.c machines?
• Conduct electricity between armature and fixed brushes
• Converts altenatingemf into unidirectional emf and vice versa
7. Distinguish between shunt and series field coil constructions.
Shunt field coils are wound with wires of small cross section and have more number of turns. Series field coils are wound with wires of larger cross section and have less number of turns. (ee6352 electrical engineering and instrumentation Important questions)
