Branch Current Analysis & Nodal Voltage Analysis Explained Using a Simple Example (With Experiment)

In this recording of a live-streamed lecture, I give a brief overview over circuit calculation and network analysis methods. We then take a more detailed look onto branch current analysis and nodal voltage analysis using a simple example. In this example the equivalent resistance or total resistance of a resistive circuit consisting of five resistors shall be determined.
