What is the primary advantage of using a digital multimeter?

• A. It is less expensive than analog meters
• B. It provides accurate voltage, current, and resistance readings
• C. It requires less maintenance than other tools
• D. It is lighter and more portable

Answer: (B)

Using a digital multimeter is primarily advantageous because it provides accurate voltage, current, and resistance readings. Digital multimeters utilize advanced technology to display measurements numerically, which helps eliminate the potential for human error in interpreting readings. The digital format also tends to have a greater precision and resolution compared to analog meters, which rely on a needle and scale that can be harder to read accurately, especially for small changes in measurement. This accuracy is particularly important in electrical work, where even small discrepancies can lead to significant issues. Accurate readings are essential for troubleshooting, system design, and ensuring that electrical systems operate safely and efficiently. The other options mentioned may present some benefits, such as cost or portability, but they do not surpass the critical role of measurement accuracy that digital multimeters provide.
