Which of the following best describes a VOM?

  1. A device for measuring temperature

  2. A multimeter for measuring volts, ohms, and milliamps

  3. A specific type of ammeter

  4. An advanced digital display meter

The correct answer is: A multimeter for measuring volts, ohms, and milliamps

A VOM, orVolt-Ohm-Meter, is best described as a multimeter that measures volts, ohms, and milliamps. This device serves multiple functions, allowing it to measure electrical properties such as voltage (volts), resistance (ohms), and current (milliamps), making it essential for troubleshooting and testing electrical systems. The reference to "multimeter" highlights its versatile capabilities, as opposed to a singular measuring function like a temperature measurement device or a specialized ammeter. This versatility is why option B accurately captures the essence of what a VOM is designed to do. The other choices, while they may describe different instruments or functions, do not encapsulate the broad measurement capabilities of a VOM. Therefore, option B stands out as the most precise description.
