Find VA and VB using Node-Voltage method in the given circuit.(a) 2.5V, 3.6V(b) 2.87V, 3.25V(c) 2.65V, 3.47V(d) 3.15V, 2.76VI got this question during an interview for a job.The origin of the question is The Node-Voltage Method and Dependent Sources and Some Special Cases topic in chapter Techniques of Circuit Analysis of Electric Circuits

Answer»

Correct option is (b) 2.87V, 3.25V

To explain: Node A:VA/2 + (VA-1)/2 + (VA-VB)/1 =2

Node B:(VB-2)/2 + (VB-VA)/1 =1

 By SOLVING the above equations required VOLTAGES are obtained.
