Welcome to ohm's law made easy for series circuits. By the end of this course, students will be comfortable with ohm's law, the series circuit rules and the math calculations for automotive electrical series circuits. Ohm's law expresses the relationship between voltage, current and resistance in an electrical or electronic circuit. By knowing any two values, voltage and current, voltage and resistance, or current and resistance, the third value can be calculated mathematically. Understanding the math behind these relationships can help you in your diagnostic thought process. Series circuits are used when lower than source or battery voltage is desired or when you want components to share the source voltage. Parallel circuits are used when we want each device to receive the full source voltage. In automotive circuits, most are parallel because more often than not, it is desired that each component receives full battery or source voltage. This course is geared toward automotive students, beginning electronics students and do it yourselfers that desire a solid foundation and understanding of series circuits and ohm's law. This course does more than just show you a formula and tell you about a concept, it walks you through the thought process, the steps, and the reasoning behind them. This course provides practice examples and detailed explanations of how the answers were calculated and determined. Understanding ohm's law math can help students recognize incorrect voltage measurements and become better at troubleshooting and electrical diagnostics. Let's get started!
