The question might be simple for you guys but the problem is that it is not for ME !! I have a circuit and I have to determine the node voltages by Nodal Analysis method. And the one which I learned was in cases when we had a current source, I could simply write the equations using KCL. But I am totally confused in such cases when I have a voltage source, and I have been asked to do the same (i.e calculate the nodal voltages). Please HELP OUT !!
