The row formed at node ‘c’ in the cut set matrix in the following figure?(a) -1-100+1 -100(b) 00+100-1-10(c) +1000 +100+1(d) -1000-100-1The question was posed to me in semester exam.The doubt is from Cut-Set and Tree Branch Voltages in chapter Methods of Analyzing Circuits of Network Theory

Answer»

The correct ANSWER is (b) 00+100-1-10

Best EXPLANATION: The direction of the cut SET at node ‘c’ is AWAY from node ‘c’. So the CURRENT direction of I3 is same as cut set direction. So it is +1.Similarly for all other currents.
