Components

Formulae

After balancing circuit, equating real part we have:
`frac(R4)(R3) = frac(C1)(C2) + frac(R2)(R1)`
Also, equating imaginary part we have:
`f = frac(1)(2pisqrt(R1R2C1C2))`

Instructions

Wien Robinson's frequency Bridge
    •Pick up four resistances,two capacitors, a ac voltage source and a detector from the toolbox.

    •Connect the elements as shown in the figure to form a Wien Robinson's frequency Bridge.

    •After making the circuit click on check circuit button to check the connections
    •Now enter the values of resistors, capacitors and AC voltage source and click on the submit button.

    •Repeat the experiment until the bridge gets balanced.

    •After balancing the bridge, unknown frequency will popup.
