A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel . It usually has a high resistance so that it takes negligible current from the circuit.
"A science fiction story is a story built around human beings, with a human problem, and a human solution, which would not have happened at all without its scientific content." [13] Basil Davenport. 1955. "Science fiction is fiction based upon some imagined development of science, or upon the extrapolation of a tendency in society." [14] Edmund ...
Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
Science is concerned with the accurate description of reality, and voltmeters are part of the reality that science has to describe. Whether physics textbooks and physics teaching give correct explanations of what voltage really is, and whether they write down a correct formal definition of voltage, are other issues.
A 19th century version of a voltameter. A voltameter or coulometer is a scientific instrument used for measuring electric charge (quantity of electricity) through electrolytic action.
