Electrical Engineering

  1. Determine the current in the circuit by calculating the currentin the resistor. Note: We will use I (and VR since ithas the same phase) for reference throughout our analysis(VR/R = I).
  1. Determine the capacitance of the circuit from its reactance,the current calculated above, and the frequency of the source(VC/I = XC).
  1. Determine the inductance of the circuit from three differentvoltage measurements, the current calculated in step 1, and thefrequency of the source, following the instructions below carefully(this can be complicated).
  1. Determine the phase of VLR with respect toVR using the law of cosines (VLr2=VLR2 + VR2 –2VLRVR cos(α)).
  1. Determine the fraction of VLR due to VLalone (VL = VLRsin(α)).
  1. Determine the inductance of the circuit from its reactanceusing the current determined in step 1 and the VLdetermined above (VL/I =XL).
  1. Determine the loss in the inductor and write it as a resistanceusing the current found in step 1

           (Vr = VLRcos(α) – VR and r =Vr/I).

  1. Determine the phase between the source voltage and the current(φ = tan-1 [(VL –VC)/(VR+Vr)]).
  1. Calculate the resonant frequency of the circuit from the valuesyou determined for L and C
