Direction: Consider the circuit Assume diodes are ideal.

If V₁ = V₂ = 10 V, then output voltage V₀ is:

1. 9 V
2. 9.474 V
3. 4 V
4. 8.943 V

Correct Option: B

Since both the terminal voltage V₁ and V₂ is at 10 V and connected through the same 1 kΩ resistance. So in this case we assume that both the diodes are ON.
Apply. KCL at node A

V₀ – 0	+	V₀ – V₁	+	V₀ – V₂	= 0
9		1		1

or V₀ =	V₁		+	V₂
	1			1

	1	+	1	+	1
	9		1		1

=	10		+	10		= 9.474 V
	1			1

	1	+	1	+	1
	9		1		1

Check assumption

I_D₁ = I_D₂ =	V₁ – V₀	=	V₂ - V₀	=	10 – 9·474
	1 kΩ		1 kΩ		1 kΩ

I_D₁ = I_D₂ = 0.526 mA > 0
Therefore Diode D₁ and D₂ both are ON.
Hence alternative (B) is the correct choice.
