In the Wien Bridge oscillator circuit shown in figure, the bridge is balanced when $\dfrac{R_3}{R_4}=\dfrac{R_1}{R_2}\, \: \: \omega =\dfrac{1}{\sqrt{R_1C_1R_2C_2}} \\$ $\dfrac{R_2}{R_1}=\dfrac{C_2}{C_1}, \: \: \omega =\dfrac{1}{R_1C_1R_2C_2} \\$ ... $\dfrac{R_3}{R_4}+\dfrac{R_1}{R_2}=\dfrac{C_2}{C_1}, \: \: \omega =\dfrac{1}{R_1C_1R_2C_2}$
