Which tool would you typically use to check the voltage in a circuit?

• A. Wrench
• B. Multimeter
• C. Pliers
• D. Soldering iron

Answer: (B)

A multimeter is the appropriate tool for measuring voltage in a circuit. It is a versatile instrument that can measure not only voltage but also current and resistance, making it essential for troubleshooting and testing electrical systems. When checking voltage, a multimeter can provide accurate readings in both AC and DC circuits, allowing technicians and electricians to determine if circuits are functioning properly. In contrast, tools such as a wrench, pliers, and a soldering iron serve very different purposes. A wrench is used for turning nuts and bolts, pliers are designed for gripping and manipulating objects but cannot measure electrical parameters, and a soldering iron is utilized for joining electrical components to a circuit board or wire connections. These tools do not have the capability to measure voltage, which highlights why the multimeter is the correct choice for this task.
