2. (45 pts) Use nodal analysis to find the node voltages, Va and Vb. Show and label each of the following node voltage method steps on your paper for your solution: a. Redraw the circuit and annotate resistors with voltage polarities. b. Select a reference node or ground and choose node voltage variables for each node where you do not know the node voltage. c. Determine an equation (only in terms of constants and node voltage variables) for each current going into or out of each unknown node. d. Write KCL at each unknown node using the equations for the current you determined in part c. e. Simplify the equations and solve them simultaneously, if necessary, for the node voltages.
