What does a multimeter measure?

A multimeter is a versatile instrument used primarily in electrical and electronic troubleshooting to measure various parameters. It is specifically designed to measure voltage (the electric potential difference), current (the flow of electric charge), and resistance (the opposition to the flow of current in a circuit).

These measurements are crucial for diagnosing electrical issues, verifying circuit designs, and ensuring that components are functioning correctly. By providing readings for voltage and current, a multimeter can help electricians and technicians ensure that circuits are safe and operating within specified limits. The ability to measure resistance allows users to test components such as resistors, diodes, and circuit continuity.

While other measuring tools may cover pressure, temperature, torque, power, speed, noise levels, and vibration, these are not functions of a standard multimeter. Therefore, the choice highlighting voltage, current, and resistance accurately reflects the primary capabilities of a multimeter.
