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