What tool is primarily used to measure voltage in electrical circuits?

• A. Clamp meter
• B. Analog multimeter
• C. Digital multimeter
• D. Voltage tester

Answer: (C)

The digital multimeter is primarily used to measure voltage in electrical circuits because it provides accurate and clear readings in digital format, making it easy to interpret results. This tool is versatile and can measure not only voltage but also current and resistance, which makes it essential for comprehensive electrical inspections.

Digital multimeters are preferred for their precision and the ability to display readings in multiple ranges. They often come with various functions, such as data hold and auto-ranging, which enhance usability. These features allow inspectors to conduct thorough assessments of electrical systems, ensuring safety and compliance with regulations.

While other tools like clamp meters and analog multimeters also measure voltage, they might not provide the same level of accuracy or ease of use as digital multimeters. Voltage testers are typically used for quick checks and may not provide a precise measurement, which limits their utility in detailed inspections.
