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

1. R₃ = R₁ , ω = 1
  R₄ R₂ √R₁C₁R₂C₂
2. R₂ = C₂ , ω = 1
  R₁ C₁ R₁C₁R₂C₂
3. R₃ = R₁ + C₂ , ω = 1
  R₄ R₂ C₁ √R₁C₁R₂C₂
4. R₃ + R₁ = C₂ , ω = 1
  R₄ R₂ C₁ R₁C₁R₂C₂

Correct Option: C

When bridge is balanced, z₁ z₄ = z₂ z₃

⇒	R₃	=	R₁	+	C₂	and ω	1
	R₄		R₂		C₁		√R₁R₂C₁C₂
