To study and Measure the Voltage, Current Power and Power factor in parallel RLC circuit.

Instructions

  • !!! Click on labels to delete connections for the corrusponding node.
  • Make connections as per the instructions given below.
    • 1->23, 2->24
    • 3->25, 4->26
    • 25->5, 6->9, 6->10
    • 8->12, 12->14, 14->16
    • 7->18, 18->20, 20->22
    • 11->17, 13->19, 15->21
  • Now, Check the connections by clicking on ‘CHECK’ button.
    • If the connections are ‘Invalid connections’ click on corresponding node to remove the connection.
    • And if the connections are ‘Right Connections’ then follow the below steps.
  • Turn on the MCB.
  • Switch on the variac by clicking on the button.
  • Click on the variac knob to set the voltage at 220V.
  • Now, Click on ‘ADD’ button to add the readings in the observation table.
  • In Calculations section, We have to manually calculate the values by using the formula.

\[R = \frac{V_{R}}{I}\] \[X_{L} = \frac{V_{L}}{I} = 2 \pi fL\] \[X_{C} = \frac{V_{C}}{I} = \frac{1}{2 \pi fC}\]
\[Z = \frac{1}{\sqrt{(\frac{1}{R})^2 + (\frac{1}{X_{L}} + \frac{1}{X_{C}})^2}}\] \[\cos\phi = \frac{R}{Z}\]
