Question

Correct. Kirchhoff's junction rule states that the sum of the magnitudes of the currents directed into a junction equals the sum of the magnitudes of the currents directed out of the junction. Here, this rule implies that I1 + I3 = l2. The following four equations are supposed to result from applying Kirchhoff's junction rule to the four junctions in the circuit shown in the drawing. However, one of the equations is written incorrectly. Which one is it? I4 + I5 = I1 I1 + I2 = I3 l6 = I3 + I5 I2 = 14 + l6

Explanation / Answer

As Kirchoff's junction rule suggests, that current leaving a junction is equal to correct going towards the junction...
option 'b' is incorrect
the correct solution should be I3 + I1 = I2
