Which of the following tools is commonly used for measuring electrical current?

The multimeter is a versatile tool commonly used for measuring electrical current, voltage, and resistance in circuits. When set to the appropriate mode, it can provide accurate readings of current flowing through a circuit, making it an essential instrument for electrical work. This measuring capability helps electricians and technicians diagnose issues, check the functionality of components, and ensure safety during electrical maintenance.

In contrast, while a voltmeter is specifically designed to measure voltage, and it plays a crucial role in electrical diagnostics, it does not measure current directly. A screwdriver serves an entirely different function, primarily for fastening or loosening screws, and is not utilized for measurement. A pencil, while useful for sketching or taking notes, has no application in measuring electrical parameters. Understanding these distinctions is important for using the right tool for the job in electrical work.
