What is voltmeter? What is the function of this?​

What is a voltmeter? A voltmeter is an tool that measures the difference in electric potential between two locations in an electric circuit. It is connected in a parallel manner. It has a high resistance and draws very little current from the circuit. Analog voltmeters use a galvanometer and a series resistor to move a pointer around a scale in proportion to the voltage detected. Amplifier-based meters can detect voltages as low as a few microvolts. An analog-to-digital converter is used in digital voltmeters to display voltage numerically. Voltmeters come in a variety of forms, some of which are powered separately (for example, by a battery) and others which are powered by the voltage source being measured. Generators and other stationary devices are monitored using instruments permanently positioned in a panel. Standard test devices used in electrical and electronics work include portable instruments that can measure current and resistance using a multimeter. Any measurement that can be converted to a voltage, such as pressure, temperature, flow, or level in a chemical process plant, can be displayed on a properly calibrated meter.

Explanation:

What is voltmeter? what is the function of this?
 - A voltmeter is an instrument utilized for estimating the voltage or likely distinction between two places in an electrical circuit. The voltmeter is associated equal 100% of the time.  It usually has a high resistance so that it takes negligible current from the circuit. A voltmeter is an instrument utilized for estimating the voltage or likely distinction between two places in an electrical circuit. Today, a ton of the voltmeters are computerized which given the readings as mathematical showcases. Nonetheless, simple structures are likewise accessible and this sort of voltmeter gives readings wherein a pointer begins moving toward some path showing voltage on a scale. Computerized voltmeters are favored in light of the fact that they by and large have a higher request of precision than simple voltmeters.
