A(n)_______ is a device that can be used to measure several different electrical characteristics.

The correct answer is the option that includes both the digital multimeter (DMM) and the multimeter because both devices are capable of measuring various electrical characteristics. A digital multimeter is a specific type of multimeter that provides readings in digital format, offering the same versatile functionality found in analog multimeters but with greater accuracy and ease of reading.

Multimeters, whether digital or analog, are designed to measure voltage, current, and resistance, making them versatile tools for electrical measurements. Their ability to switch between different measurement modes allows users to assess multiple electrical properties using a single device, which is particularly valuable in troubleshooting and diagnostics in electrical systems.

In contrast, while an oscilloscope is an essential tool in analyzing the waveform of electrical signals, it does not measure the same variety of characteristics as a multimeter. Oscilloscopes primarily provide visual representations of voltage over time, focusing on signal changes rather than providing direct measurements of voltage, current, or resistance like a multimeter would. Therefore, the inclusion of both DMM and multimeter in the answer recognizes their shared capability while distinguishing their specific functions from those of an oscilloscope.
