**Nodal Analysis**

**Sample Circuit: 1 Unknown Node**

Consider three lossy voltage sources in parallel as a context for outlining the
procedure of mesh analysis. Note that there are actually 2 nodes, but the bottom
one has been grounded to 0.0 V, so there is only one unknown nodal voltage.

**Step 1: Assignment of Nodal Voltage**

Assign a variable name to all nodes with unknown voltages.

**Step 2: Apply KCL to Each Node**

Assume that all currents flow away from the node. Apply KCL.

**Node 1:**

**Step 3: Solve for the Unknown Voltages**

In this case, there is only one equation involving one unknow voltage, which may be
found with simple algebraic manipulation.
