Which tool would a lineman use to accurately measure electrical current?

A lineman would use a multi-meter to accurately measure electrical current because a multi-meter is designed to measure multiple electrical properties, including current, voltage, and resistance. It can function as both an ammeter and a voltmeter, allowing a lineman to take various readings and troubleshoot electrical systems effectively.

When measuring current, the multi-meter is set to the appropriate current setting (AC or DC, depending on the system), giving a direct reading of the current flowing through a circuit. This versatility makes the multi-meter an essential tool for linemen who need to address multiple aspects of electrical systems.

Other tools, such as the ammeter, are specifically tailored for measuring current but may not have the multifunctional capabilities of a multi-meter. The ohmmeter measures resistance and is not suitable for current measurement, while the voltmeter focuses solely on voltage levels. Therefore, the multi-meter stands out as the most comprehensive and useful tool for a lineman in measuring electrical current and other related electrical properties.
