Find the voltage (V) at node 1 in the circuit shown.(a) 5.32(b) 6.32(c) 7.32(d) 8.32This question was posed to me in an online quiz.Query is from Nodal Analysis in division Methods of Analyzing Circuits of Network Theory

Answer» RIGHT choice is (b) 6.32

Explanation: At node 1, (1/1+1/2+1/3)V1-(1/3)V2 = 10/1. At node 2, -(1/3)V1+(1/3+1/6+1/5)V2 = 2/5+5/6. On solving above equations, we get V1=6.32V.
