This video tutorial explains how to analyze a simple series circuit by determining the total voltage, equivalent resistance, and total current. It covers the calculation of current through each resistor and the voltage drop across them using Ohm's law and Kirchhoff's voltage rule. The tutorial emphasizes the importance of understanding these concepts for effective circuit analysis.

What is the primary characteristic of a series circuit?
