Find the voltage (V) at node 2 in the circuit shown below.(a) 2.7(b) 3.7(c) 4.7(d) 5.7This question was posed to me by my school principal while I was bunking the class.The above asked question is from Nodal Analysis in portion Methods of Analyzing Circuits of Network Theory

Answer»

Right option is (C) 4.7

The EXPLANATION is: 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 V2=4.7V.
