An ammeter is a device that measures the amount of current that passes through a circuit. It uses a galvanometer as its main component. 

The first ammeters were direct-reading instruments, but today they have largely been replaced by digital meters. While an ammeter and a multimeter share some similarities, they are, in fact, two different instruments.

The Multimeter

A multimeter is a measuring instrument that combines several measurement functions in one unit. The device contains a number of electrical test functions, including continuity testing and measuring of electric voltage. 

It is also called a multitester. A multimeter is an invaluable tool for any electronics hobbyist or professional.

There are several types of multimeters, each with different capabilities. The most common type is the analog multimeter, which uses an analog display. The next most common is the digital multimeter, which uses a digital display, followed by the oscilloscope, which is primarily used in laboratory settings.

Knowing more about Ammeters

The word “ammeter” comes from the Greek word “ammeter” (ametros, meaning “unlimited” or “unmeasured”) and the word “meter” (metron, meaning “measure”), so an ammeter is a type of measuring instrument used to measure electrical current.

An ammeter is a specialized type of instrument that is used to measure the electrical flow of amperes. 

Unlike voltmeters and ohmmeters, which are designed to measure direct current and direct current resistance, respectively, an ammeter is designed to measure alternating current.

Ammeters are helpful in many different situations, from simple power measurements on lighting circuits to more complex measurements on industrial power systems.

Other important things to know about Ammeters:

  • It has different ranges and different scales than the average multimeter, making it a useful tool for measuring certain types of currents.
  • A current-measuring instrument, called an ammeter, measures the quantity of electricity (in amperes) flowing in a circuit. The voltage drop across the Ammeter is proportional to the current and is therefore usually small.
  • Ammeters are usually designed to have low internal resistance so that they consume a negligible amount of power.
  • An ammeter will have a positive and negative lead which are inserted into the circuit being tested.
  • Ammeters are also commonly used to measure the current in batteries. Ammeters can also be used to measure the charge in a capacitor.
  • Ammeters use the same measurement units as a voltmeter; the unit of current in the International System of Units (SI) is the ampere.

The Ammeter measures the quantity of current. The Ammeter has the value of current by rotating the needle on a circular scale. The Ammeter is generally used in the circuit to check the current of the load along with voltage and resistance.

In the lab, an ammeter, a voltmeter, and a multimeter are connected in parallel and are used to check the current, voltage, and resistance of the circuit.

Ammeter and Multimeter: The Difference

An ammeter is a type of multimeter. A multimeter is a tool that measures multiple different electrical properties. An ammeter is a type of multimeter because they both measure multiple things. 

Some multimeters can measure amperage, others measure voltage, and yet others measure resistance. Of all the different multimeters you can buy, they all have different features. 

One of the most common questions asked by beginners is: “Which one is better? An ammeter or a multimeter?” The answer to this question is something that only you can find out. 

By this, I mean that there is no correct answer to the question. Instead, you should find out which one works best for you.

When comparing these two instruments, you need to keep in mind that what you need to measure will determine which one you should get. 

The Ammeter is an instrument used to measure the amount of current that is going to a circuit. The current is measured in amperes. 

The multimeter, on the other hand, is used to measure voltage, resistance, and the amount of charge that is in a device.

Multimeters and ammeters are both measuring devices. But they get the job done in different ways. As the name implies, an ammeter measures amperage. 

This is the flow of electrical current in a circuit. It is a basic electronics tool that is used to measure current.

The multimeter, on the other hand, is a bit more complex. It has several different settings that allow it to measure different parameters. 

It measures voltage, resistance, and current. It is also used to test diodes, transistors, and other electronic components. The next time you need to measure an electrical current or voltage, you’ll know what to use. 

Finding the Best Ammeter

When you need to measure current in circuits, you need an ammeter. An ammeter is an instrument that measures the electric current in a circuit. 

For most hobbyists, the Ammeter they need is a relatively low voltage version, typically measuring from 10 to 500mA.

For most ammeters, you will need to observe a few things when you are buying them. For a current measurement of less than 200mA, the Ammeter should have a full scale of at least 20mA. For higher currents, the scale should be at least 50mA for the full scale.

The Ammeter is an essential part of any electronics engineer’s toolkit, capable of measuring current in circuits and measuring the voltage across a component. The voltage measurements an Ammeter can make are not as varied as a Multimeter, but this might not be an issue when working on lower voltage circuits. 

It is essential to use an Ammeter with an appropriately rated input current. The resistance of the meter’s internal wiring limits the input current, and anything above this will damage the meter.


Of all the electronic devices in the world, the Ammeter is one of the most indispensable. It is used to measure the flow of current in electrical circuits. 

Ammeters are used when the current is either too large or too small to be measured by a voltmeter or a continuity tester. It is also used to measure the charge in a capacitor, which is a static electricity device. 

Although ammeters are often used as a vital diagnostic tool, they may also be used as functional parts in a circuit. Ammeters are useful like any other meters and are used extensively in industry and also in electronic circuits.
