Voltmeters and Potentiometers are used to measure potential difference.
2nd Answer:
Not true. While a voltmeter is indeed used to measure potential difference, the potentiometer is a rotating control device, like a volume control on a radio. The potentiometer is actually a variable resistor, and measures absolutely nothing.

∙ 10y agoBasically in a voltmeter there is a coil of excessive high resistance. This when connected across the supply to measure it(voltage) a negligibly small current passes through this coil which practically make no difference in the system. Though the current is very small it produces a reasonable amount magnetic torque in the coil to move a pointer which is again calibrated against a standard meter, as because there are huge numbers of turns in the operating coil. Magnetising force is the product of current and numbers of turns.

What is the electrical unit of potential difference?
Potential Difference is measured in Volts
What is the definition of potential defference?
The difference, measured in volts, in electric potential between two points.
What is the potential difference in electricity?
The potential difference in electricity is the Electromagnetic Force, in Volts, measured across the two wires that make the circuit.
Clearly distinguish between electric potential energy and electric potential?
Potential difference means the difference in the potentials at two specified points. If "potential" is mentioned without any such qualifier it usually means the potential difference between a point and the "earth" or "grounded terminal". The prefix "electric" is just a reminder we are talking electrically. But the same argument applies equally to gravitational potential.
Why is potential difference measured in volts?
Potential difference is defined as follows: every coloumb of charge that passes through this difference will gain (or lose, depending on direction and signs) 1 joule of energy. This unit, joule/coloumb, is simply called the volt.
What is the potential difference measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
What is the electrical unit of potential difference?
Potential Difference is measured in Volts
What is force measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
What are the differences between voltage and potential difference?
Voltage is the potential difference to the ground. By convention, ground potential is zero volt.The above answer is incorrect. 'Voltage', by definition, is potential difference. It has nothing to do with being measured with respect to ground -in fact potential difference (voltage) cannot be measured with respect to anything.
Is voltage measured in volts?
Voltage, along with electric pressure, electric tension, and electrical potential difference is measured in units of electric potential. This can be joules per coulomb or volts.AnswerFirst of all, there is no such thing as a 'voltage difference'. Voltage is already a 'difference', as it is an alternative name for 'potential difference'! 'Voltage difference', therefore, would mean 'potential difference difference', which makes no sense!The unit for potential and potential difference (voltage) is the volt, which is equivalent to a coulomb per second.
What kind of difference is measured in volts?
Volts are a measure of electric potential difference.
What is used to measure potential difference?
A Volt meter is used to measure potential difference (a.k.a. voltage). Potential difference is measured in units called: Volts (V).
How is the potential difference across a resistor measured?
by using voltmeter
What is potencial difference measured in?
The unit of measure is the Volt Potential difference is basically electrical "pressure" (an excess of electrons). Volt.....The unit of electric potential. Named after the Italian physicist Alessandro Volta (1745- 1827). The potential difference is the difference in charge at the poles of a current source The volt (symbol: V) is the SI derived unit of electromotive force, commonly called "voltage". It is also the unit for the related but slightly different quantity electric potential difference (also called "electrostatic potential difference"). ... en.wikipedia.org/wiki/Volt
What is the definition of potential defference?
The difference, measured in volts, in electric potential between two points.
What is the potential difference in electricity?
The potential difference in electricity is the Electromagnetic Force, in Volts, measured across the two wires that make the circuit.
Which unit is used when measuring electrial potential?
Potential difference is measured in Volts (shown as (V) or sometimes (E))
