SPECIFICATION

55715 Experimental Set Up has been designed specifically to study series and parallel resonance in an LCR circuit (air core Inductance, Two Decade condensers and resistance) and damping effect by using resistances and air core Inductance with metal (ferromagnetic) plate (i) at fixed frequency by varying condenser (C) and (ii) by varying frequency. 
Practical experience on this set up carries great educative value for Science and Engineering Students.
 
OBJECT
  1. Study of series and parallel resonance in LCR circuit.
  2. Observe damping effect by using air core Inductance with metal (ferromagnetic) plate.
    1. At fixed frequency by varying C.
    2. By varying frequency.
  3. Observe damping effect by using resistances.
 
OBJECTS:
  1. To plot the series resonance curve in LCR circuit (air core inductance, two decade condensers and circuit resistance) at fixed frequency by varying condenser (C). Observe damping by a metal (ferromagnetic) plate along with air core Induct ance, find out new resonance curve by varying condenser (C)
  2. To plot the series resonance curve in LCR circuit by varying frequency. Observe damping by a metal plate along  with air core Inductance, find out new resonance curve by varying frequency (f).
  3. To plot the parallel resonance curve in LCR circuit (air core Inductance, two decade condensers and circuit resistance) at fixed frequency by varying condenser (C). Observe damping by a metal (ferromagnetic) plate along with air core Inductance, find out new resonance curve by varying condenser (C).
  4. To plot the parallel resonance curve in LCR circuit by varying frequency. Observe damping by a metal plate along with air core Inductance, find out new resonance curve by varying frequency (f).
  5. To plot the series resonance curve in LCR circuit by varying frequency. Observe damping effect by using resistances.
