Which electrical values are typically measured by a multimeter?

A multimeter is an essential tool used in aviation mechanics to measure various electrical values, and it typically measures voltage, current, and resistance.

Voltage is the electrical potential difference between two points and is crucial for understanding the performance of electrical systems. Current, measured in amperes, indicates the flow of electrical charge and is vital for determining load requirements and ensuring safety in circuits. Resistance, measured in ohms, quantifies how much a material opposes the flow of electricity, and this information is essential for diagnosing issues in electrical components and circuits.

These three measurements are foundational to troubleshooting and maintaining electrical systems, especially in aviation where safety and functionality are paramount. While other measurements like capacitance, frequency, power, and inductance are important in specific contexts, they are not typically the primary values measured by standard multimeters. This focus on voltage, current, and resistance reflects the core functions of the multimeter in diagnosing and repairing electrical systems in aviation.
