In the network shown in the given figure, which of the following

In the network shown in the given figure, which of the following equations would represent the equation for loop 3?

1. – I₁ + 4 I₂ + 11 I₃ = 0
2. I₁ + 4 I₂ + 11 I₃ = 0
3. – I₁ - 4 I₂ + 11 I₃ = 0
4. I₁ + 4 I₂ + 6 I₃ = 0

Loop equation is
(I ₃ – I₁) 1 + 6 I₃ + (I₃ – I₂). 4 = 0
∴ – I₁ – 4 I₂ + 11 I₃ = 0
