About the video
This lesson covers the techniques for testing resistance and continuity using a digital multimeter (DMM). You’ll understand the significance of resistance values and how they indicate the health of various electrical components like fuses, light bulbs, and heating elements. The video demonstrates practical applications, such as checking for continuity in wires, determining if a fuse is blown, and measuring the resistance of light bulbs. Additionally, you’ll learn how to use Ohm’s Law to calculate current and power based on resistance and voltage readings. Mastering these testing methods is crucial for diagnosing electrical issues and ensuring the integrity of circuits in the field. To get started, go to the Lesson Content tab and click on the video.
