Why is it recommended to use a multimeter in electrical troubleshooting?

Using a multimeter in electrical troubleshooting is important because it allows you to accurately measure voltage, current, and resistance in circuits. This capability is essential for diagnosing electrical issues, as it provides quantitative data about the circuit's performance and functionality.

By measuring voltage, you can check if the correct voltage is being supplied to different components, which is crucial for their operation. Measuring current helps in understanding how much electricity is flowing through the circuit and can indicate if there are any overloads or short circuits. Resistance measurements can help identify faulty components or connections by showing whether they are within acceptable limits.

This information is invaluable for pinpointing problems, ensuring safety, and guiding repairs, making the multimeter an indispensable tool for any technician engaged in electrical work. Other options, while relevant in different contexts, do not offer the direct troubleshooting benefits that measurement provides.
