Reference Node and Node Voltages
Reference Node
In circuits, we usually label a node as the reference node also called ground and define the other node voltages with respect to this point. The reference node has a potential of
by definition. The following symbol is used to indicate the reference node:
The Reference Node Symbol As mentioned, the selection of the reference node is arbitrary. However, a wise selection can make the solving easier. As a general rule, it is usually chosen to be
