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

To check the voltage drop in a circuit, a voltmeter is the appropriate tool to use. A voltmeter is specifically designed to measure the difference in electric potential between two points in a circuit. When checking the voltage drop, you connect the voltmeter probes across the component or section of the circuit you wish to measure. This enables you to determine how much voltage is being lost as electrical current passes through that component, which is crucial for diagnosing circuit performance or identifying issues within the system.

A multimeter can also measure voltage, current, and resistance, but its primary function depends on the specific setting it is switched to. In this case, choosing a voltmeter directly emphasizes the task of measuring voltage drop specifically. Meanwhile, an ohmmeter measures resistance and is not suitable for voltage drop measurements, and an ammeter measures current flowing through a circuit, which does not directly relate to voltage drop.
