A voltammeter is a type of scientific instrument used for measuring electrical quantities. These are measured in two SI units: the electric potential (volt) and the electricity's quantity (coulomb).
Electrical current can be measured with an Ammeter. The units used are amps.
An instrument for detecting and measuring electricity especially as an ionization of the ionization of air by radioactivity.
As a VOM (volt-ohm meter) is one type of electrical measuring instrument, it is unclear how to answer this question. It is almost as if you had asked "What are the advantages and disadvantages of the banana as compared to the edible plant part?"
The official definition of the word bolometer is "a sensitive electrical instrument for measuring radiant energy."
An instrument for measuring in volts the differences of potential between different points of an electrical circuit.
A low resistance ohmmeter is used
It measures the current.
You adjust the measuring instrument :)
Meter is the general name for any measuring instrument. Such as an electricity meter, or an odometer on your car. But if you mean the metre as in measuring systems, then surveyors, mountaineers, engineers, and so on.
