A voltmeter is used to measure the difference in electric potential ("voltage")
between two points, usually but not necessarily in an electrical circuit..
There are two main types of digital voltmeters: integrating digital voltmeters and integrating analog-to-digital converter voltmeters. Integrating digital voltmeters are based on the principle of integrating the input voltage to measure it accurately, while integrating ADC voltmeters use an analog-to-digital converter to convert the input voltage to a digital reading.
Voltmeters provide a direct, difference of potential measurement or test.
Voltmeters are connected in parallel in a circuit.

Voltmeters typically have a rectangular or square shape and feature a digital or analog display. Digital voltmeters show readings on an LED or LCD screen, while analog voltmeters have a dial with a needle that indicates the voltage level. They often include input jacks for connecting test leads and may have buttons for selecting different measurement settings. Overall, their design is functional, focusing on readability and ease of use.
voltmeters
Mechanics use a wide variety of tools to ply their trade. They use cutters, screwdrivers, wrenches, hammers, voltmeters, and other more specialized tools.
ammeters measure the flow of electricity voltmeters measure the pressure of electricity
voltmeters
The positive terminals in voltmeters and ammeters are generally indicated by a red coloring and a + (plus) symbol. Negative is generally black and - (minus).

Voltmeters are connected to simple series circuits the same way they are connected to any circuit. They are connected in parallel with the portion of the circuit for which you wish to measure the voltage drop.
