ARRL Technician Practice Exam

Which of the following measurements are commonly made using a multimeter?

1. Resistance and capacitance

2. Voltage and resistance

3. Current and capacitance

4. Inductance and voltage

The correct answer is: Voltage and resistance

A multimeter is a versatile instrument used to measure electrical values in various applications. The most commonly made measurements using a multimeter include voltage, resistance, and current. Voltage measurement allows you to measure the potential difference between two points in a circuit, making it essential for troubleshooting and confirming that circuits are operating within their specified voltage levels. Resistance measurement helps in assessing the integrity of components and wires in a circuit, detecting broken connections or faulty components. While some multimeters do offer features for measuring capacitance, it is not as universally applicable as voltage and resistance measurements. Capacitance measurement is typically found in more advanced or specialized multimeters and is not as fundamental as voltage and resistance for general troubleshooting. Options that include current and capacitance or inductance and voltage reflect measurements that are not as universally applicable in basic multimeter tasks. Therefore, the choice that emphasizes voltage and resistance represents the most common and essential functions of a multimeter in electrical testing and troubleshooting.
