The average multimeter can measure up to 20V in voltage levels. Yet many builds, especially in R&D and electronic work, use less than 200mA of current. This detail underscores the key role multimeters play in electrical testing and troubleshooting. Knowing how to use a multimeter is essential, not just for techs and engineers, but also for beginners exploring electrical concepts. …
