Tutorial on the Node Voltage Method - Part 2

Node a, the reference node, is now marked with the ground symbol. Note that node a has the most branches (4), and that it has the most voltage sources connected to it (one -- no other node has more than one voltage source connected to it).

You will now have to label most nodes with unknown voltages. If node c were such a node, you would label it as Vc. For one node, you don't have to specify an unknown because it is possible to specify the actual voltage.

Which node (b through g) is it?
