Multimeter vs. Voltmeter: Understanding the Differences and When to Use Each

Discover the differences between multimeters and voltmeters and when to use each. Explore their functionalities, applications, and make informed choices for your electrical projects.

Multimeters and voltmeters are indispensable instruments in the toolkit of professionals and hobbyists who work with electronic and electrical circuits. Despite having similarities, they cater to distinct functionalities and applications. Here, we venture into the nuanced differences between multimeters and voltmeters, emphasizing their capabilities, functionalities, and optimal use cases.

Introduction to Voltmeters

To comprehend the differences, we first delve into understanding what voltmeters are. Voltmeters are devices specifically designed to measure the voltage difference between two points in an electronic or electrical circuit. Voltage is essentially the electric potential difference. Which is vital in determining the force driving the electric current in a circuit. Here’s a deeper dive into its functionalities:

Analog and Digital Voltmeters

Voltmeters come in analog and digital variants. While the analog voltmeters use a moving-coil meter to indicate the voltage, digital voltmeters exhibit voltage readings on a digital display.

Voltage Measurement

Voltmeters measure the voltage which is pivotal in diagnosing circuits and understanding the distribution of electrical potential across various components.

Simplicity and Specificity

Being specialized instruments, voltmeters offer simplicity and specificity in voltage measurement tasks. Making them straightforward tools for those focused on voltage measurements exclusively.

Introduction to Multimeters

Multimeters, on the other hand, are versatile instruments that can function as voltmeters, but they also incorporate the functionalities of ammeters and ohmmeters, which measure current and resistance, respectively. Let’s explore the functionalities of multimeters:

Multi-functional Tool

Multimeters can measure various parameters including voltage, current, resistance, and sometimes even more advanced parameters such as capacitance, temperature, frequency, etc.

Analog and Digital Multimeters

Like voltmeters, multimeters also come in both analog and digital types. The digital variants, known as digital multimeters (DMMs), are generally preferred due to their higher accuracy and ease of reading.

Suitability for Complex Diagnostics

Multimeters are suitable for complex diagnostics in electronic circuits, as they allow for multiple types of measurements using a single instrument.

Comparative Analysis: Multimeters vs. Voltmeters

Having individually dissected both multimeters and voltmeters, it is time to juxtapose them to carve out their distinctive features and capabilities:


  • Voltmeters: Exclusive measurement of voltage across two points in a circuit.
  • Multimeters: Multi-faceted measurement functionalities encompassing voltage, current, resistance, and often much more.

Complexity and Versatility

  • Voltmeters: Less complex, catering to specific voltage measurement needs.
  • Multimeters: More versatile, allowing for a wide variety of measurements, making them an all-encompassing tool for most electrical measurement needs.

Learning Curve

  • Voltmeters: Easier to use for beginners focusing solely on voltage measurements.
  • Multimeters: Slightly steeper learning curve, owing to the broader set of functionalities and settings.

Practical Applications and Use Cases

Delving further, we analyze the practical applications and cases where these instruments find their utilization, enhancing our understanding of where to use which instrument:


  • Educational Settings: Due to its simpler functionality, it can be a go-to device in educational settings where the primary focus is to teach voltage measurements.
  • Basic Troubleshooting: Voltmeters can be used in basic troubleshooting in electrical circuits where voltage measurement can give sufficient insights into the problem.


  • Professional Electrical and Electronics Work: Multimeters find extensive use in professional environments owing to their versatile functionalities, aiding in comprehensive diagnostics and troubleshooting.
  • Research and Development: In R&D settings, multimeters are indispensable, offering multifaceted measurement capabilities for a thorough analysis of circuit behaviors.
  • Home Maintenance and DIY Projects: Multimeters are a favorite tool for DIY enthusiasts and home maintenance tasks involving electrical appliances and circuits, offering a one-tool solution for most measurement needs.

Making the Right Choice: Multimeter or Voltmeter?

Selecting between a multimeter and a voltmeter hinges on the specific requirements of the user. Here, we delineate factors that can aid in making an informed choice:

Nature of the Task

  • Specialized Voltage Measurements: For tasks exclusively revolving around voltage measurements, a voltmeter would suffice.
  • Multifaceted Electrical Work: For a more complex and multifaceted electrical diagnostic and troubleshooting task, a multimeter would be more suitable.


  • Cost-Effective: Voltmeters tend to be more cost-effective due to their limited functionalities.
  • Investment in Versatility: While multimeters might come at a higher price point, they offer a versatile range of functions, making them a valuable investment for serious hobbyists and professionals.

Future Prospects

  • Learning and Upgrading: If one envisages delving deeper into the world of electronics and electrical circuits, starting with a multimeter could be a futuristic choice, allowing room for learning and upgrading skills.


In conclusion, both multimeters and voltmeters have their own set of unique functionalities catering to different levels of complexity and varieties of tasks. While a voltmeter remains a specialized instrument for measuring voltage, a multimeter stands as a versatile powerhouse offering a plethora of measurement functionalities. The choice between the two should reverberate with the user’s needs, expertise level, and the nature of tasks at hand. It is advisable to have a discerning understanding of both to make a choice that stands in harmony with one’s requirements, paving the path for efficient and effective work in electrical and electronic endeavors.
