Procedure
STEP 1: Pick up four resistances, two capacitors, a battery and a headphone from the Components.
STEP 2: Connect the resistances, capacitors and the battery as shown in the figure to form a Wein series bridge.
STEP 3: Click on check circuit button to check the connections.
STEP 4: Now choose R1,R2 and R3 to a fixed value and vary the value of R4 only such that ratio (R4/R3) is nearly an integer between 1 to 5, and fix it to the value where the sound frequency changes from loud beap to pleasant sound.
STEP 5: Hit the submit button and make the resistance arm ratio mentioned in the alert equal to the arm ratio not mentioned as per the balancing condition
STEP 6: Now observe the reading of digital meter as it drops to zero hit"Submit" button.
STEP 7: Repeat the experiment by changing the values of resistances and note atleast 3 readings.
