To Study and measure the Voltage, Current, Power and Power factor in parallel RLC circuit

Instructions

  • Step 1: Make connections as per the instructions given below.

    • 1-23, 2-24
    • 3-25, 4-26
    • 5-25, 6-9, 6-10,
    • 7-18, 8-11
    • 11-13, 13-15, 12-17
    • 18-20, 14-19, 16-21
    • 20-22, 26-7

  • Note: Click on the label to delete connection for the corresponding node.

  • Step 2: 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.

  • Step 3: Turn on the MCB.

  • Step 4:Switch on the variac by clicking on the button.

  • Step 5:Click on the variac knob to set the voltage at 220V.

  • Step 6:Now, Click on ‘ADD’ button to add the readings in the observation table.

  • Step 7:In Calculations section, We have to manually calculate the values by using the formula and verify it with the help of Verify button.
