In our second installment of the series we take a look at Nodal Analysis for technicians. Nodal analysis is a means of determining the voltage present at a node of interest with respect to a specified reference point. Many technicians have difficulties creating valid Ohm’s Law representations for the KCL (Kirchhoff’s Current Law) node equations when trying to perform this type of circuit analysis.

Today’s discussion focuses on Euler’s number and the utility of the related natural logarithm or “ln” function as they pertain to technician level circuit analysis. Once we have discussed the nature of Euler’s number and the related base “e” natural log function, we will move on to take a look at an example of their practical application for technicians when performing circuit analysis tasks.

What is Euler’s Number ?
