Which tool performs various tasks related to electrical circuits?

The electrical multimeter is an essential tool used to measure the voltage, current, and resistance in electrical circuits. It plays a crucial role in diagnosing issues within those circuits by allowing technicians and engineers to take precise measurements. By checking for continuity, measuring voltage levels, and assessing current flow, users can effectively troubleshoot problems, verify that components are functioning correctly, and ensure that circuits are operating safely.

In contrast, the dust mask is designed for respiratory protection against dust and other airborne particles, making it unrelated to electrical tasks. The drift punch is a tool used in metalworking to align holes or to drive pins, serving a very different purpose from electrical measurements. Lastly, the eye bolt is a fastener that provides a loop for fastening and securing components but does not interact with electrical circuits. Therefore, the multimeter stands out as the tool specifically designed for tasks related to electrical circuits.
