A node is usually labelled as the reference node also called ground and the other node voltages are defined with respect to this point. The reference node has a potential of 0 V by definition.

Problem 1-12: Using Voltage Sources to Determine Node Voltages
A three-node circuit is solved by using the voltage of voltage sources. The nodal analysis is not used since there are enough voltage sources to determine all node voltages.
