what is voltmeter plzz solve this karthik and Hardik .it is urgent
Answers
A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. A voltmeter in a circuit diagram is represented by the letter V in a circle.
Voltmeters are made in a wide range of styles. Instruments permanently mounted in a panel are used to monitor generators or other fixed apparatus. Portable instruments, usually equipped to also measure current and resistance in the form of a multimeter, are standard test instruments used in electrical and electronics work. Any measurement that can be converted to a voltage can be displayed on a meter that is suitably calibrated; for example, pressure, temperature, flow or level in a chemical process plant.
Happy independence day
Coming to your question
A voltameter or simply you say a voltage meter measures the potential difference ,Voltage of two poibts ,You might have seen in Ac Or refrigerator stabilizor which is used for measuring the voltage or Potential difference
