When measuring voltage in a circuit, which instrument would be appropriate?

A multimeter is appropriate for measuring voltage in a circuit because it is specifically designed to measure various electrical parameters, including voltage, current, and resistance. In voltage measurement mode, the multimeter can display the voltage level present across two points in an electrical circuit, which is essential for troubleshooting and ensuring proper operation of electrical systems.

For accurate voltage readings, a multimeter is typically connected in parallel with the component or circuit segment being tested. This functionality makes it versatile and widely used by electricians and technicians. The ability to switch modes allows users to measure not only DC and AC voltage but also current and resistance, which adds to its practicality.

In contrast, while instruments like oscilloscopes are capable of measuring voltage, they are primarily used to visualize waveforms rather than for standard voltage measurement. Ammeters are designed specifically to measure current, and clamp meters, although useful for measuring current through a conductor without direct contact, do not measure voltage directly. Thus, the multimeter stands out as the most suitable instrument for voltage measurement in a circuit.
