In the Wien Bridge oscillator circuit shown in figure, the bridge is balanced when

  1. $\frac{R_3}{R_4}=\frac{R_1}{R_2}\: \:, \:\:\:\:  \omega =\frac{1}{\sqrt{R_1C_1R_2C_2}}$ 
  2. $\frac{R_2}{R_1}=\frac{C_2}{C_1}\:\: , \:\:\:\:  \omega =\frac{1}{R_1C_1R_2C_2}$
  3. $\frac{R_3}{R_4}=\frac{R_1}{R_2}+\frac{C_2}{C_1}\:\: , \:\:\:\: \omega =\frac{1}{\sqrt{R_1C_1R_2C_2}}$ 
  4. $\frac{R_3}{R_4}+\frac{R_1}{R_2}=\frac{C_2}{C_1}\:\: , \:\:\:\:  \omega =\frac{1}{R_1C_1R_2C_2}$
