R-L-C Circuit Analysis

  Procedure:

  1. Closed the Switch(K). Set Input Voltage Vin=220V.
  2. Set power supply voltage (VS) at=0V. Keep all the resistance, Inductance, capacitance at maximum position and switch on the circuit.
  3. Adjust the voltage across the circuit (VS) to about 70 V and note current(I), Vs, VL, VC, VR and power(W) from the meters. Click on " Fill the Table " button.
  4. Adjust the rheostat for several settings and repeat step 2.
  5. Adjust the rheostat to the maximum setting and change the capacitance to 0uF, 140 uF, 70uF and change the inductance to 0mH, 30 mH, 60mH repeat step 2.
  6. Draw phasor diagrams showing VR, VL, VC, VS, & I for different sets of readings.
