Observe the figure and find the correct relation from the four given options?

• A. i1 + i2 + i4 = i3 + i5 + i6
• B. i4 + i2 + i3 = i1 + i5 + i6
• C. i1 + i2 + i3 = i4 + i5 + i6
• D. i1 + i2 + i6 = i4 + i5 + i3

Answer: (D)

According to Kirchhoff’s law states that the current entering a node is always equal to the current leaving a node.
From the above Diagram
Current Flowing towards the Point: I1, I2, I6 
Current Flowing Away from the Point: I3, I4, I5
Hence I1 + I2 + I6 = I3 + I4+ I5
