How does one typically measure the output voltage of a circuit?

Using a multimeter in voltage mode is the standard method for measuring the output voltage of a circuit. A multimeter is specifically designed for measuring electrical values, and in voltage mode, it can accurately assess the potential difference between two points in a circuit. This allows for determination of both AC and DC voltages, making it a versatile tool in electronics.

When set to voltage mode, the multimeter connects in parallel across the component whose voltage you want to measure. The device will display the voltage value, which can help in troubleshooting or validating circuit operation.

In contrast, an oscilloscope can also visualize voltage, primarily used for analyzing waveforms and observing how voltages change over time, but it is not the typical tool for direct voltage measurement in a straightforward manner. A current probe measures current flow in a conductor, while an ammeter is designed specifically for measuring current, not voltage. Thus, the usage of a multimeter in voltage mode stands out as the most straightforward and conventional approach for measuring output voltage in a circuit.
