Model: B3




The purpose of this experiment is

  • To investigate the characteristics of the series resonant circuit.
  • To verify that, at resonance, the current is maximum and is determined by the resistance in the circuit.
  • To demonstrate that the voltage across the LC combination is minimum.
  • To prove that the individual voltage across L or C can be higher than the applied voltage.
  • To investigate how changing the values of L,C and R affect the characteristics of the circuit.
  • To demonstrate that maximum voltage always occurs across L or C at resonance.
  • To demonstrate that when R is increased, the amplitude of voltage across the capacitor is decreased.
  • To demonstrate that the bandwidth increases by increasing resistance.
  • NO POWER SUPPLY IS REQUIRED since this trainer is constructed out of passive components.
