Question

Find all the node voltages in the given circuit containing dependent sources.

(a) 10V, 20V, 30V, 40V

(b) 15V, 25V, 32V, 45V

(c) 10V, -20V, 30V, -40V

(d) -15V, 25V, -35V, 45V

I got this question in a job interview.

My question is taken from The Node-Voltage Method and Dependent Sources and Some Special Cases topic in division Techniques of Circuit Analysis of Electric Circuits

Answer 1

Right option is (a) 10V, 20V, 30V, 40V

The best I can explain: At supernode: VC-VB=5iX

    And ix = (VB-VA)/5. On solving remaining nodes and forming equations, the required voltage values at nodes are obtained.
