Electrical instruments are devices used to measure, monitor, and control electrical quantities such as voltage, current, and resistance. Common examples include multimeters, which can measure multiple electrical properties, and oscilloscopes, which visualize electrical signals over time. These instruments are essential in various fields, including engineering, electronics, and telecommunications. These tools help ensure that electrical systems operate safely and efficiently. By providing accurate readings, electrical instruments assist technicians and engineers in diagnosing issues, conducting experiments, and maintaining equipment. Proper use of these instruments is crucial for both safety and performance in electrical applications.
