A digital multimeter is a test instrument used to measure two or more electrical values, primarily resistance, current, and voltage (in volts and amps) (ohms). For technicians working in the electrical and electronic industries, it is a typical diagnostic tool. Voltage, current, and resistance are just a few of the electrical stimuli that a digital multimeter, or DMM, measures and verifies. It combines the functions of a voltmeter, an ammeter, and an ohmmeter and is common diagnostic equipment used by technicians and electrical engineers.
Analog and Digital Multimeters: A device known as an analogue multimeter is used to measure certain electrical quantities like current, voltage, resistance, etc. Adigital multimeter is a tool used to test a variety of electrical parameters, including current, voltage, resistance, capacitance, diode values, and transistors, among others.
Multimeters are complex instruments that can measure a variety of parameters in various ways.
A "shunt resistor" is used while attempting to measure current. You connect the shunt resistor in series with the current you wish to measure, the current through the resistor causes a voltage drop, you measure the voltage drop, and then you use Ohms Law (I = V/R) to calculate the current through the resistor.
A voltage metre, usually referred to as a voltmeter, it is a device that measures the voltage, or potential difference between two points in an electrical or electronic circuit. Direct current (DC) circuits are the intended usage of some voltmeters, whereas alternating current (AC) circuits are the intended use of other voltmeters.
The Operating Concept Since each element in a parallel circuit receives the same voltage, the voltmeter and the load also receive the same voltage; as a result, the voltmeter measures the voltage across the load. To get the best voltmeter for your projects do check out our website.
There are certain multimeters that can measure humidity, duty cycle, pressure, frequency, temperature, etc. with advanced characteristics. Digital Multimeter with Probe is the best multimeter.

5. What is a Raspberry Pi Multimeter?
This tiny device connects to your Raspberry Pi via USB and offers ADC (analogue to digital conversion) inputs.
6.What are multimeters used for?
A multimeter can be a handheld device for basic fault detection and field service work, or a bench instrument with extremely high accuracy. They can be used to troubleshoot electrical issues in a wide range of industrial and household devices, such as electronic equipment, motor controls, domestic appliances, power supplies, and wiring systems.
7.Which is better analog or digital multimeter?
Both digital and analogue multimeters are excellent tools for measuring electrical current, voltage, and resistance.
The digital multimeter wins the race in terms of features, readings, and ease of use.
However, analogue multimeters have their advantages and should be considered if you need a low-cost multimeter solution.
8.What is voltmeter used for?
A voltmeter, also known as a voltage metre, is a device that measures the potential difference, or voltage, between two points in an electrical or electronic circuit, direct current or alternating current voltages on a scale commonly expressed in volts, millivolts, or kilovolts. Some voltmeters are designed for direct current (DC) circuits, while others are for alternating current (AC) circuits. Radio frequency (RF) voltage can be measured using specialised voltmeters. Many voltmeters are digital and display readings numerically.
9.What is principle of voltmeter?
A voltmeter's basic principle is that it must be connected in parallel to the circuit in which the voltage is to be measured. Because a voltmeter is constructed in such a way that it has a very high resistance value, a parallel connection is used.
