The maindifferencebetween avoltmeterand an electrometer is their sensitivity and the range of measurements they can take. A voltmeter is used to measure the voltage or potential difference between two points in a circuit, while an electrometer is used to measure small electric charges or potential differences.A voltmeter is a type of electrical meter that measures thevoltageor potential difference between two points in a circuit. It is typically less sensitive than an electrometer, and is designed to measure larger voltages, typically in the range of 1 volt to several thousand volts.An electrometer, on the other hand, is a type of electrical meter that isdesignedto measure small electric charges or potential differences. It is much more sensitive than a voltmeter and can measure voltages as low as a few microvolts or even less.Electrometersare typically used in scientific and research applications, where small charges or potential differences need to be measured accurately.Insummary, the main difference between a voltmeter and an electrometer is their sensitivity and the range of measurements they can take. Avoltmeter is used to measure larger voltages, while an electrometer is used to measure small electric charges or potential differences.To know more aboutvoltmeter and electrometerrefer here:brainly.com/question/17517149##SPJ11...
