Ohm’s law is an expression of the relationship between current, voltage and resistance in an electrical or electronic circuit.  Knowing any two values, such as voltage and current, voltage and resistance, or current and resistance, allows you to calculate the third value mathematically.  Understanding the math behind these relationships can help you improve your diagnostic thought process and allow you to narrow down electrical faults more quickly.  Series circuits are useful for when you want components to share the source voltage or when lower than source or battery voltage is desired. Parallel circuits are used when we want each device to receive the full source voltage.  Series parallel circuits are used when a combination of the series and parallel traits are needed.  This course features the first of the three types of circuits, the series circuit.

The course begins with some keywords and terms to get you up to speed on the language and terminology of electrical circuits.  Ohm’s law is then presented in a graspable manner to allow for quick and easy progress through the Ohm’s law practice example lessons.  Ample time is spent illustrating and explaining the series circuit rules to prepare you for the series circuit math calculations and exercises that follow.  Determining the order of the math calculations is spelled out in a way that takes the guess work out of the process.  Numerous practice examples are provided and reviewed.  The course also offers a few recorded live demo lessons to demonstrate series circuits using real components to help solidify your understanding.  Understanding Ohm's law math is useful to help students discern incorrect voltage measurements,  and generally become better at electrical diagnostics and troubleshooting.

This course is geared toward automotive students, beginner electronics students and DIY-ers who are looking for a solid foundation in series circuits and Ohm’s law. More than just showing formulae and concepts, this course walks you through the thought process, steps and reasoning behind them. Join me, Steve Liguori, in this course on ‘Series Circuit Rules and Ohm’s Law’ and start your journey toward a satisfying grasp of the three types of circuits used in basic automotive and electronics. Once you finish the series course, look for my parallel circuits and series parallel circuits courses to complete your journey. Let’s get started!
