When analysing electrical circuits, there are many analysis techniques and theorems available to you. One technique that will work for just about any electrical circuit with any number of voltage sources, current sources, and resistors is nodal analysis.
In this video, I go through the steps involved in nodal analysis while working through an example circuit with two nodes.
Video Timeline
00:10 - Introduction
01:25 - Step 1 (optional): convert voltage sources to current sources
02:09 - Step 2: Identify all the nodes and pick a reference node
02:42 - Step 3: Assign voltage labels to the nodes
03:32 - Step 4: Assign current labels in all the branches
04:15 - Step 5: Create a Kirchoff's Current Law (KCL) equation for each node
05:15 - Step 6: Rewrite the KCL equations in terms of voltages and resistors
08:00 - Step 7: Solve the equations to determine the node voltages
08:50 - Check your work
