Difference Between Multimeter and Voltmeter

You probably take a pretty vague idea near the departure between a multimeter and a voltmeter, but you’re non quite sure and y’all exercise not exactly understand how these ii work. We look at these 2 instruments in particular and assistance y’all sympathise how the two differ. To better understand let’s get started.


What is a Voltmeter?

Voltmeter is an electrical instrument that is used to measure voltage of either direct or alternating electric current in volts. It accurately measures the difference in electric potential between two points in a circuit. While some voltmeters are designed to work well with straight current, some voltmeters are better for measuring alternate electric current. And then in that location are some voltmeters that can read both. A voltmeter works on the same basic principle as an ammeter, except a voltmeter has a high resistance. It is designed in such a way that when connected in parallel to the excursion for measuring voltage it does not take observable current.

A voltmeter non only measures voltage just also electric current and resistance. A standard voltmeter used in the laboratories employs electromechanical machinery for functioning and typically measures in the g – 3000 volts range. A voltmeter measures voltage by passing current through a resistance. It is designed in such a mode and then equally to offer minimum disturbance to the circuit. The voltage is represented using the letter ‘Five’, and the sensitivity of a voltmeter is usually specified in ohms/volts.


What is a Multimeter?

If you detect a faulty appliance in your home and you are not sure what’south causing the fault, the best way to find out is to use a multimeter. A multimeter is a handheld musical instrument, more like electronics troubleshooting tool that you can use to diagnose the defective part of a excursion. A multimeter basically checks the electrical resistance inside a circuit. In fact, information technology can be used to mensurate multiple electrical properties. A typical multimeter tin measure voltage, current and resistance. More expensive versions can measure other parameters such every bit capacitance, transistor gain, and diode frontward voltage.

A multimeter comes in two different types: an analog and a digital. A digital multimeter is like your digital wristwatch where the measured values are shown on a digital display, allowing y’all to read them easily with a relatively smaller gamble of making an fault. An analog multimeter, on the other hand, uses a needle along a scale to measure voltage, resistance, frequency, current, and signal power. Auto-ranging is nonetheless another handy feature to look for in a multimeter if you’re willing to spend some extra bucks. This sets the exam range automatically.

Difference between Multimeter and Voltmeter

Role

– A voltage meter or voltmeter is a handheld tool used to measure voltage of either straight or alternating electrical current in volts. Information technology basically measures the difference in electrical potential betwixt 2 nodes of an electrical circuit. A multimeter is essentially a multi-purpose troubleshooting tool that you tin employ to diagnose the defective part of a circuit. It mainly checks the electrical resistance inside a circuit and combines the functions of other meters, such as a voltmeter, an ammeter, and an ohmmeter, all in ane bundle.

Measurements

– A voltmeter non only measures voltage only also current and resistance. While some voltmeters are designed to work well with direct current, some voltmeters are ameliorate for measuring alternating electric current. A multimeter measures voltage, current and resistance. More than advanced versions (or the expensive ones) can as well measure other parameters such as capacitance, transistor proceeds, and diode forward voltage.

Applications

 – A voltmeter can be used for the following purposes: voltage sensing, voltage measurement, electric testing, laboratory testing, and electronic industry. A multimeter is a multi-purpose musical instrument that assumes the functions of other meters such as voltmeters, ammeters, and ohmmeters. The primary applications of a multimeter include Air conditioning/DC current measurement, AC/DC voltage measurement, capacitance measurement, frequency measurement, battery testing, temperature and environmental applications, diode checking, and so on.

Summary

In a nutshell, a voltmeter is a simple testing tool that is used to mensurate the difference in electric potential between two points in a excursion. A voltmeter works on the same bones principle every bit an ammeter, except a voltmeter has a high resistance. A multimeter, on the other manus, is a multipurpose troubleshooting tool that tin be used to exam the lacking part of a excursion. A multimeter basically checks the electric resistance within a circuit. In fact, it can be used to measure multiple electrical properties and can assume the functions of different meters, such every bit a voltmeter, an ammeter, and an ohmmeter.

Is a multimeter the same thing as a voltmeter?

A multimeter is a multipurpose tool that can presume functionalities of other meters, such as an ammeter, an ohmmeter, and a voltmeter. And then, a multimeter can likewise human action as a voltmeter. Notwithstanding, a voltmeter cannot exist used as a multimeter substitute.

Can a multimeter be used every bit a voltmeter?

Yes, a multimeter tin certainly be used as a voltmeter. In fact, it tin can be used to measure out multiple electrical properties, including voltage, resistance and electric current.

Why does voltmeter or multimeter not requite more than accurate reading of voltage?

About handheld digital multimeters or voltmeters are pretty accurate, only the standard ones are typically measured with±iii% accurateness. The accuracy is affected by many factors though, including input impedance, temperature, and variations in the power supply voltage.
