What does a voltmeter do and how is it used to measure electrical potential difference?
A voltmeter is a device used to measure the electrical potential difference between two points in a circuit. It works by connecting the voltmeter in parallel with the component or circuit being measured. The voltmeter then displays the voltage difference in volts, allowing the user to determine the potential difference between the two points.
How can one determine the potential difference between two points in a circuit?
To determine the potential difference between two points in a circuit, you can use a voltmeter. Connect the voltmeter across the two points you want to measure and the reading displayed on the voltmeter will indicate the potential difference between those two points.
What is the purpose of a voltmeter in a circuit?
the purpose of a voltmeter is used to measure voltage in a circuit
What is the difference between a galvanometer and an ammeter?
A galvanometer is a device used to detect small electric currents, while an ammeter is a device used to measure the strength of electric currents. The main difference is that a galvanometer is more sensitive and used for detecting small currents, while an ammeter is used for measuring larger currents.
What is the physical quantity measured by an voltmeter?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
A galvanometer can be converted into a voltmeter by placing?
a high resistance in series
Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
Uses of voltmeter?
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..

What resistance value is add to convert a galvanometer into a voltmeter?
It depends on the resistance of the galvanometer and the current required to reach full scale. A 100 ohm meter requiring 1 milliampere would require 99.9 KOhms in series to become a 100 volt voltmeter.
How is a voltmeter connected in the circuit to measure the potential difference between two points?
The voltmeter is connected in parallel between the two points whose potential difference is required.
High resistance in parallel connected with galvanometer to form voltmeter?
That won't work. To convert an ammeter (a galvanometer is a very sensitive type of ammeter) you connect a high value resistor in series with it.
What should you do to convert a galvano meter into volto meter?
Connect a large but precisely known resistance in series with the galvanometer. For example, if you connect a 1-Megohm resistor in series with it, then the galvanometer will indicate 1 microampere of current when it's connected across a potential difference of 1 volt ... quite a sensitve voltmeter.
What is a voltmeter?
a calibrated instrument for measuring the potential difference between two points.
What is the purpose of a voltmeter in a circuit?
the purpose of a voltmeter is used to measure voltage in a circuit
