The Beginners Guide to Testing Electrical Circuits


No multimeter experience needed. Students should own or have access to a meter for skills practice.


The Beginner’s Guide to Testing Electrical Circuits combines clear explanations of electrical circuits, components, and values with detailed demonstrations and labs on using test instruments competently and safely. The instruction also covers common circuit and component troubleshooting and the role of a multimeter in that process.  Designed for students and beginners, the curriculum is also a great refresher and skill builder for those familiar with electrical testing. Whether you are a student, electrician, technician, engineer, or hobbyist, The Beginner’s Guide to Testing Electrical Circuits will improve your knowledge and competence when using digital multimeters.The instruction begins with lessons on basic electrical circuits, terminology, and theory, including Ohm’s Law. These are then applied to test instruments and how they function. Also included are essential safety precautions and step-by-step test procedures. Basic testing tools are demonstrated, primarily focusing on the digital multimeter. Students should have access to a meter to replicate and practice testing procedures included in the training.  The instructor, Mitch Hegman, is both a practicing master electrician and a professional instructor. Mitch understands electrical testing from both a practical and educational perspective and applies a combination classroom and “in-the-field” approach to his teaching. And early course lessons introduce and allow students to begin using and practicing with their meters as they learn about circuits and components.
